| 17:36:54 | Defiler | We prefer the latter |
| 17:36:58 | Defiler | It is more idiomatic |
| 17:37:24 | mass | sigh, i wish I could get the iphone 2 when it comes out |
| 17:37:33 | Defiler | Oh, is WWDC today? |
| 17:37:37 | mass | yeah |
| 17:37:38 | Defiler | I guess I knew that |
| 17:37:38 | NoKarma | yes |
| 17:37:45 | evan | drbrain and I are here at the coffee shop. |
| 17:37:48 | mass | 23 minutes till the second coming of the jesus phone |
| 17:38:19 | gnufied leaves the room. | |
| 17:38:34 | mass | I heard if you throw it into a bucket of water it will turn into wine |
| 17:38:36 | evan | Jesus Phone: A second way more reliable than that other guy. |
| 17:38:38 | evan | er. |
| 17:38:42 | evan | A second coming way more.. |
| 17:38:45 | mass | but I'll just recommend others try it first |
| 17:39:06 | Defiler | Mine only came with three screws though |
| 17:39:23 | mass | your phone? |
| 17:39:41 | mass | eep, bbiab |
| 17:39:41 | Defiler | I guess if you don't live in the south, you don't learn how many nails Jesus had in him from bumper stickers |
| 17:39:44 | Defiler | Like I do |
| 17:40:39 | evan | can't say that I did, no. |
| 17:40:41 | NoKarma | Defiler: so how many have it been?? |
| 17:41:24 | Defiler | 3 |
| 17:41:27 | Defiler | Hence the joke |
| 17:41:41 | Defiler | That my jesus phone only came with three.. oh never mind :) |
| 17:42:32 | evan | heh |
| 17:42:39 | evan | Defiler: so the mouth is good? |
| 17:43:06 | NoKarma | oh, hah |
| 17:43:11 | Defiler | Yeah. My dentist is the man |
| 17:43:18 | NoKarma | I'm not that good at religion, heh |
| 17:44:59 | Defiler | He apparently speaks worldwide about cosmetic dentistry or some shit |
| 17:45:27 | Defiler | I've made up a backstory about him where he could have been a marine sniper, but felt the dental calling |

| 17:47:01 | nexcastellan | How do I fix a git error message, "cannot rebase: your index is not up-to-date" |
| 17:47:23 | evan | you have stuf in your index |
| 17:47:33 | evan | ie, you've done 'git add ...' |
| 17:47:34 | Defiler | do a "git diff origin" |
| 17:47:38 | Defiler | to see |
| 17:47:48 | evan | nexcastellan: best way is to just use 'rake git:pull' |
| 17:47:58 | evan | it will stash so everything works right. |
| 17:48:07 | nexcastellan | rake git:pull fails, that's where I get the error. :) |
| 17:48:44 | evan | does 'git status' say you have files in the top list? |
| 17:49:17 | evan | in the 'Changes to be committed:' |
| 17:49:39 | nexcastellan | I think it's because I'm trying to commit just one file but I've modified another couple. Should be easy to fix, thanks. |
| 17:49:46 | evan | k |
| 17:49:52 | Defiler | yeah, you can't pull until everything has been committed |
| 17:50:03 | evan | yep. |
| 17:50:08 | evan | you need to commit first |
| 17:50:10 | nexcastellan | Git's frustrating. :) |
| 17:50:16 | evan | you'll learn. |
| 17:50:29 | evan | it's certainly different than other systems. |
| 17:50:31 | nexcastellan | We should all go back to rcs. Just kidding. |
| 17:50:33 | Defiler | I've come to like it, myself |
| 17:50:36 | Defiler | but it was irritating at first for sure |
| 17:50:44 | Defiler | and I don't use the rake tasks |

| 19:18:55 | manveru | heya |
| 19:19:14 | manveru | are there any plans to port 1.8.7 (1.9) Enumerator? |
| 19:19:49 | evan | don't we have an enumerator builtin? |
| 19:19:51 | evan | i thought we did |
| 19:19:55 | evan | or maybe i'm thinking of enumerable. |
| 19:20:08 | wvdschel enters the room. | |
| 19:20:10 | evan | manveru: the answer is yes, since the 1.8.7 one is in C |
| 19:20:13 | manveru | no, there is enumerator |
| 19:20:13 | evan | we'll write one in ruby. |
| 19:20:21 | manveru | but it's the old one |
| 19:20:31 | evan | ah |
| 19:20:35 | evan | we'll have to figure out how to migrate |
| 19:20:44 | manveru | nods |
| 19:20:45 | evan | ie, we don't want to make it incompatible |
| 19:21:00 | evan | i'm not sure if the core team knows if the new 1.8.7 version is compat or not with the old 1.8 version |
| 19:21:07 | manveru | i think it's forward compatible |
| 19:21:26 | evan | if so, i think we'll go ahead and do it. |
| 19:21:32 | evan | if someone commits it, we'll take it |
| 19:21:37 | manveru | ok |
| 19:21:40 | manveru | should be fun :) |
| 19:21:58 | manveru | i might need a ruby version to support older MRI |
| 19:22:51 | scudwork enters the room. | |
| 19:23:23 | manveru | i think the new enumerator is just a bit more merged with Generator |
| 19:23:49 | manveru | i.e. providing #next and #rewind |
| 19:25:00 | anonuser | Morning |
| 19:25:30 | evan | manveru: ah. well, i'm happy if people stop using Generator personally |
| 19:25:34 | evan | the impl. is so icky. |
| 19:25:41 | manveru | hehe |
| 19:25:51 | manveru | i had fun today, 1.8.7 segfaulting on File.expand_path |
| 19:26:19 | evan | ug. |
| 19:28:37 | manveru | lol |
| 19:28:43 | manveru | * Use of this method is not discouraged. Use Kernel#enum_for() instead. |
| 19:29:28 | dfg59 enters the room. | |
| 19:30:03 | anonuser | manveru, where did you find that? |
| 19:30:11 | manveru | enumerator.c |
| 19:30:17 | anonuser | Engrish-gold? |
| 19:30:19 | manveru | doc for initialize |
| 19:33:02 | drbrain | I think it was patched recently |
| 19:33:29 | anonuser | Woo iPhone 3G was officially unveiled. |
| 19:33:40 | tarcieri | yeah finally |
| 19:34:31 | NoKarma | yay |
| 19:34:59 | NoKarma | so nice |

| 19:38:52 | anonuser | ah |
| 19:38:57 | tarcieri | heh |
| 19:39:07 | tarcieri | how did I guess this channel would be watching the keynote liveblogged? :) |
| 19:39:24 | NoKarma | hehe |
| 19:39:34 | anonuser | heh |
| 19:39:49 | anonuser | And GPS support :D |
| 19:40:00 | NoKarma | yay |
| 19:40:10 | NoKarma | going to be my next gadget, for sure! |
| 19:41:43 | manveru | what's the deal with initialize/initialize_copy ? |
| 19:41:49 | dfg59 leaves the room. | |
| 19:43:23 | NoKarma | initialize_copy is used for dup |
| 19:43:29 | evan | yeah |
| 19:43:46 | Defiler | Man I guess I am buying one of these iPhones |
| 19:43:51 | manveru | ok... |
| 19:43:52 | Defiler | How do I buy one? Heh. |
| 19:43:57 | tarcieri | is |
| 19:44:04 | tarcieri | I'm going to go to the AT&T store |
| 19:44:09 | tarcieri | which will be pain |
| 19:44:16 | manveru | another problem is... all the iterators in 1.8.7, when given no block, return Enumaterator now |
| 19:44:17 | nexcastellan | No iPhone 3G for Canada? |
| 19:44:35 | manveru | *Enumerator |
| 19:44:35 | evan | manveru: not all |
| 19:44:43 | evan | they've just put it into a few methods. |
| 19:44:52 | manveru | a few? :) |
| 19:44:55 | evan | like 5 or so on Array |
| 19:44:56 | evan | yeah |
| 19:44:56 | anonuser | nexcastellan, Canada is covered. |
| 19:45:00 | evan | it's explicit |
| 19:45:04 | nexcastellan | Okay, good. Thanks. :) |
| 19:45:15 | evan | if you look at the changelog, they say which the added it to |
| 19:45:20 | dctanner leaves the room. | |
| 19:45:20 | manveru | sure |
| 19:45:21 | evan | and you can grep the source and see |
| 19:45:26 | manveru | evan: but it's more than a few methods |
| 19:45:32 | evan | i think it's only like 10 methods in all. |
| 19:45:42 | anonuser | evan, not sure, I caught the tail end of the conversation with rue (i think) but is there a problem with an rb_funcall in an Init_ method of a C extension? |
| 19:46:29 | NoKarma | 199$ for an 8GB iPhone! |
| 19:46:36 | NoKarma | holy cow :D |
| 19:47:00 | Defiler | Wait no I need a much more expensive model as a status symbol! |
| 19:47:01 | tarcieri | NOT TOO SHABBY |
| 19:47:01 | Defiler | don't stop |
| 19:47:15 | NoKarma | lol |
| 19:47:29 | drbrain | $300 for 16G, and it comes in white, optionally |
| 19:47:34 | evan | Defiler: get a jewel case for it. |
| 19:47:35 | drbrain | how's that for a status symbol? |
| 19:47:38 | tarcieri | awww |
| 19:47:40 | tarcieri | JULY? |
| 19:47:49 | NoKarma | uly 11 |
| 19:47:53 | Defiler | Garrhhhg I need it now it is hurting already |
| 19:47:54 | NoKarma | *July |
| 19:47:58 | Defiler | WHY GOD |
| 19:48:06 | tarcieri | I was ready to buy one NOW |
| 19:48:12 | NoKarma | same here :'( |
| 19:48:18 | Defiler | urge.. growing flaccid.. with time.. |
| 19:48:40 | Defiler | The Jean Michele-Jarre music I am playing is helping me ride it down |
| 19:48:42 | manveru | evan: delta ruby/src/ruby % egrep -ri 'return_enumerator' . | wc -l |
| 19:48:44 | manveru | 76 |

| 19:49:20 | drbrain | how to pimp your phone ^^ |
| 19:49:25 | manveru | i can't even count that many iterators in my head... |
| 19:50:00 | evan | manveru: wow, the changelog was WAY wrong then. |
| 19:50:19 | manveru | i've been following the svn logs, and there's been tons of work |
| 19:50:49 | evan | well, then we have to discuss it. |
| 19:52:37 | manveru | right now rubinius is heading for 1.8.6 compatibility, right? |
| 19:54:29 | chopmo enters the room. | |
| 19:55:03 | evan | manveru: yeah |
| 19:55:11 | evan | we have to make a decision about 1.8.7 |
| 19:55:31 | Defiler | ruby-core doesn't seem like they are going to retract those features, right? |
| 19:55:39 | evan | no. |
| 19:55:47 | drbrain | they are 1.9 transition features |
| 19:55:51 | manveru | they are supposed to make the curve to 1.9 smoother... |
| 19:55:56 | Defiler | So I guess we are stuck implementing them |
| 19:56:08 | Defiler | Unless we want to declare that 1.8.7 is a fork of 1.8.6 |
| 19:56:09 | evan | perhaps for 1.8.7, we should investigate the version overlay |

| 20:02:58 | evan | yep! now to butter up the wife so I can buy one. |
| 20:03:15 | chopmo leaves the room. | |
| 20:03:47 | Defiler | Shit, #rubinius could buy California |
| 20:03:50 | Defiler | That's how we roll |
| 20:04:37 | Defiler | It's pronounced 'octothorpe rubinius' yo |
| 20:04:56 | nexcastellan | What's the rubinius equivalent to rb_block_proc()? |
| 20:05:09 | Defiler | What's that do? |
| 20:05:19 | elight leaves the room. | |
| 20:05:33 | Defiler | Proc.__from_block__ takes a BlockEnvironment and turns it into a Proc |
| 20:05:41 | Defiler | but I'm just guessing from the name heh |
| 20:06:09 | evan | nexcastellan: mmm |
| 20:06:28 | evan | like Defiler said, you'll need to pass cpu->block to Proc.__from_block__ |
| 20:06:35 | evan | to create a Proc from a BlockEnvironment |
| 20:15:48 | maharg | I vote no on adopting 1.8.7 as mainline functionality in rubinius. :P |

| 21:28:28 | maharg | nokarma: because I think that 1.9 is taking things in a direction that breaks stuff for no appreciable gain, and 1.8.7 is basically an inbetween release to that end |
| 21:29:24 | ezmobius leaves the room. | |
| 21:31:36 | tarcieri | the 1.9 development process was certainly frustrating |
| 21:31:53 | tarcieri | how about you keep the language the same and switch the VM, then start experimenting with the language? |

| 21:34:01 | maharg | I actually see rubinius and jruby as a way out of the "release-break-fix" cycle ruby's been in |

| 21:42:19 | evan | nexcastellan: you want to implement RHASH() ? |
| 21:42:26 | xhanjian enters the room. | |
| 21:42:38 | nexcastellan | Yeap, that's right. RHASH() so I can get st_lookup working. |
| 21:42:51 | evan | you'll have to understand RARRAY and RSTRING fully before trying |
| 21:42:55 | nexcastellan | Presumably we don't need st_lookup to work the SAME way as in MRI, just so long as it works. |
| 21:43:16 | nexcastellan | (This is so Json can work) |
| 21:43:16 | evan | we can provide an st_lookup, but it wont be at all like the one MRI has. |
| 21:43:46 | nexcastellan | Yeah, just so long as it returns the same values under the same circumstances, right? |
| 21:43:50 | evan | right. |
| 21:43:54 | nexcastellan | Okay, let me get my thoughts in order a bit here. |
| 21:44:11 | evan | RHASH() will need to return a struct that contains fields that the code wants |
| 21:44:24 | evan | ->tbl is the only one for RHASH(), i think |
| 21:44:44 | evan | so RHASH() has to work like RARRAY, ie, allocating a struct, keeping a pointer to it, returning it |
| 21:44:53 | nexcastellan | Yeap, I got that bit. And heck, we can really stuff anything we want into tbl, so long as it is sufficient for st_lookup. For now at least. |
| 21:44:54 | evan | then we'll need a #define st_lookup fake_st_lookup |
| 21:45:01 | evan | and then define fake_st_lookup |
| 21:45:06 | evan | right |
| 21:45:07 | evan | in fact |
| 21:45:14 | evan | >tbl could really just be the object passed to RHASH() |
| 21:45:24 | nexcastellan | Hahaha, good one. |
| 21:45:35 | nexcastellan | Hehehe. |
| 21:45:49 | evan | then our fake_st_lookup will know to cast it back to VALUE |
| 21:46:04 | evan | we can't call it st_lookup directly because we don't want st_lookup to show up in the symbol table |
| 21:46:13 | evan | in case someone imports st.c into their extension (which people do) |
| 21:46:27 | evan | so we'll use the #define mask trick |
| 21:47:19 | nexcastellan | Ah, wait... would we end up calling hash_find_entry, or am I still on the wrong track? |
| 21:49:24 | rubuildius_amd64 | Evan Phoenix: c8b7beb9f; 2377 files, 7770 examples, 26834 expectations, 1 failure, 1 error; http://rafb.net/p/Aj0qgz95.html |
| 21:49:52 | evan | nexcastellan: well, we shouldn't. |
| 21:49:56 | evan | those should use rb_call |
| 21:50:06 | evan | hash_find_entry has a couple of problems |
| 21:50:16 | evan | 1) it doesn't call #hash to compute the hash value |
| 21:50:24 | evan | 2) it doesn't use #eql? to compare keys |
| 21:50:33 | evan | er. rb_funcall |
| 21:51:52 | nexcastellan | That would matter if the user overrode these? |
| 21:52:38 | anteaya leaves the room. | |
| 21:52:39 | evan | yeah |
| 21:52:46 | evan | well, not even overroad them. |
| 21:52:51 | anteaya_ enters the room. | |
| 21:52:54 | evan | we're trying to remove Hash from the VM entirely actually |
| 21:53:08 | evan | because doing it properly requires so much interaction with ruby code |
| 21:53:18 | evan | it's not a lowlevel data structure at all. |
| 21:54:00 | ezmobius enters the room. | |
| 21:54:18 | nexcastellan | You'd just implement it in Ruby? |
| 21:57:04 | ShayArnett enters the room. | |

| 22:29:53 | loincloth enters the room. | |
| 22:30:00 | anonuser | drbrain, I was thinking about getting my mind wrapped around the VM a bit more than it is now. |
| 22:30:21 | anonuser | rue, the rb_funcall crap? |
| 22:35:22 | tomy_ enters the room. | |
| 22:37:41 | rue | Yeah |
| 22:38:35 | evan | tomy_: hey there! |
| 22:38:40 | lstoll leaves the room. | |
| 22:39:06 | tomy | Hey Evan. Saw your last post about llvm. It's a fun tool, huh? |
| 22:39:15 | evan | very |
| 22:39:22 | evan | i meant to resport to your comment on my blog. |
| 22:39:29 | tomy | How your hash speed :-) |
| 22:39:31 | evan | i looked at etoile |
| 22:39:42 | evan | but didn't see where they use LLVM |
| 22:39:48 | tomy | Oh yeah, etoile is very interesting to me |
| 22:39:55 | JonathanT_ leaves the room. | |
| 22:40:04 | tomy | I'll find the link... |
| 22:40:47 | tomy | David Chisnall's blog, don't have it handy. He's contributing to clang |
| 22:41:24 | evan | hm. ok. |
| 22:41:30 | tomy | I've been playing with Hash implementations and benchmarks, and have something that kicks @ss. |
| 22:41:45 | evan | oh? written in what? |
| 22:41:57 | tomy | C++ |
| 22:42:09 | tomy | It beats the SGI/GNU hash_map. |
| 22:42:18 | evan | cool. |
| 22:42:21 | evan | where you working now? |
| 22:42:22 | StCredZero enters the room. | |
| 22:42:34 | tomy | It is based on a modified Cuckoo Hash (see wikipedia) |
| 22:42:52 | evan | nice, yeah, i've seen that. |
| 22:43:00 | tomy | I'm Working for a company called Varolii as their build and deployment engineer. |
| 22:43:09 | evan | ah, cool. |
| 22:43:17 | tomy | Gives me a lot of time to work on ahem, government projects. |
| 22:43:37 | evan | heh |
| 22:44:04 | tomy | So I use this wicked public domain has called hashlittle2. It gives two 32 bit hashes for the price of one. |
| 22:44:42 | evan | ah nice. |
| 22:45:21 | tomy | Then I segment it into four hashes. My bench mark uses ruby methods and then throws uses a novel from gutenburg to perform massive lookups. My hash is currently 15 percent faster than anything I can find on the net. |
| 22:45:35 | evan | very cool. |
| 22:45:38 | tomy | I can achieve a 97 percent fill rate! |
| 22:45:46 | evan | very cool. |
| 22:45:55 | nexcastellan | I thought cuckoo hashes could only fill to about 50%? |
| 22:45:55 | evan | we've talked about fixing up our hash |
| 22:46:03 | binary42 leaves the room. | |
| 22:46:33 | tomy | Cuckoo with two hashes only do about 50 fill, but read the linked articles on wiki. Using four hashes gets your to 97. |
| 22:46:52 | nexcastellan | Hahaha, and keeping it constant time for lookups. Of course. :) |
| 22:47:21 | tomy | I'm going to parameterize my hash into a template and then put it up somewhere with a liberal license. |
| 22:47:39 | tomy | Constant time lookups, yes |
| 22:48:15 | tomy | One of the articles goes into architecture-specific optimizations, I think it was a paper from IBM research. |
| 22:49:09 | tomy | Strangely, I got an additional five percent speed up separation keys and values into separately allocated arrays. Counterintuitive. |
| 22:49:59 | tomy | But, from what I understand about generational garbage collectors, the whole locality of reference issue change under that GC. |
| 22:50:12 | fbuilesv enters the room. | |
| 22:50:47 | evan | yep |
| 22:51:18 | tomy | Evan, have you read the Self guys paper on the Cartesian Product Algorithm? |
| 22:51:46 | evan | hm, not sure i've read that one. |
| 22:52:04 | qwert666_ leaves the room. | |
| 22:52:46 | tomy | The basic idea is to create specialized methods on the fly based on the types encountered so far, and use the types as a lookup. |
| 22:53:35 | evan | oh |
| 22:53:35 | evan | yeah. |
| 22:53:40 | evan | i have read that. |
| 22:54:57 | explody enters the room. | |
| 22:55:41 | evan | explody: hi gemstone person! |
| 22:55:49 | wycats leaves the room. | |
| 22:55:49 | tomy | It's strange that so much came out of the Self project back in the 90's, that now seems so relevant to current interest in all things dynamic (ruby, javascript,etc) |
| 22:56:04 | explody | hello fallingsnow person |
| 22:56:19 | wycats enters the room. | |
| 22:56:36 | evan | explody: :) |
| 22:57:00 | explody | Monty is standing right behind me, he says hi |
| 22:57:12 | StCredZero | A big problem with the 90's was how balkanized the OO community was |
| 22:57:16 | explody | he just posted dinner photos on flickr |
| 22:57:17 | tomy | So any reason a single LLVM based VM couldn't support Ruby and Javascript? Or rather, could Ruby be implemented with prototype-based inheritance? |
| 22:57:36 | evan | explody: ah! |
| 22:57:41 | evan | explody: whats the url? |
| 22:57:53 | moofbong leaves the room. | |
| 22:58:05 | evan | tomy_: they could most definitely be implemented inside the same VM |
| 22:58:30 | evan | I was actually going to do a blog post called "Ruby is a prototype based language (no really)" |
| 22:58:39 | explody | http://flickr.com/photos/monty_williams/sets/72157605522003510/ |
| 22:58:55 | StCredZero | You could hide the prototype-based inheritance |
| 22:59:47 | tomy | Exactly, seems like prototype based inheritance is just a superset of Ruby. |
| 23:00:06 | michaellatta leaves the room. | |
| 23:00:13 | tomy | Evan here's the hashing algorithm link. Look at lookup3.c: http://burtleburtle.net/bob/hash/index.html |

| 23:04:58 | tomy | Evan, one last link, be sure to check out his object model paper linked on this page: http://piumarta.com/software/cola/ |
| 23:05:06 | evan | :) |
| 23:05:09 | explody leaves the room. | |
| 23:05:10 | evan | i've had lunch with ian and his team |
| 23:05:18 | evan | we've been following their work closely. |
| 23:05:48 | tomy | Cool. His object model in a tiny amount of lines is really cool. |
| 23:06:07 | evan | yeah |
| 23:06:15 | evan | he's gotten in smaller from what I heard |
| 23:07:00 | tomy | I finally have a blog, and I'm putting up interesting papers as I come across them: http://my-god-its-full-of-tubes.blogspot.com |
| 23:07:16 | evan | cool. |
| 23:07:53 | tomy | Some of the partial evaluation papers I've come across are mind-bending. |
| 23:08:22 | explody enters the room. | |
| 23:08:45 | anteaya_ leaves the room. | |
| 23:08:56 | StCredZero leaves the room. | |
| 23:09:29 | maharg | I think it'd be fairer to say that any OO system is a superset of prototype based. How close you can get to a prototype model in an OO environment is going to depend on what primitives are still exposed. |
| 23:10:05 | anteaya_ enters the room. | |
| 23:10:36 | krsh leaves the room. | |
| 23:11:28 | tomy | I guess superset wasn't quite the word I was looking for. Maybe, less restrictive. Using a prototype system with the properly exposed pieces I think I could implement any other object model. |
| 23:12:43 | tomy | I like Ian's approach in that he's restricting as little as possible about the implementation. |
| 23:12:58 | evan | yeah |
| 23:14:17 | tomy | BTW, I gave up on using Rice to bind LLVM to Ruby. Somewhere around about the tenth page of template errors :-( |
| 23:14:19 | evan | I say Ruby is prototype based beacuse it has per object behaviors |
| 23:14:27 | evan | something pretty much no other class-based language has. |

| 23:16:07 | fbuilesv enters the room. | |
| 23:16:11 | evan | we use it for a builtin FFI layer |
| 23:16:18 | fbuilesv enters the room. | |
| 23:16:34 | tomy | I was always surprised this wasn't in Ruby. |
| 23:16:35 | evan | to let people connect C libraries directly |

| 23:17:11 | tomy | Lisp guys have written any C for years :-) |
| 23:17:31 | maharg | evan: smalltalk has that as well, doesn't it? |
| 23:17:41 | maharg | the whole metaclass thing is ripped right out of smalltalk afaik |
| 23:17:53 | evan | maharg: no |
| 23:18:06 | evan | in smalltalk, a metaclass/behavior only exists on instances of Class |
| 23:18:12 | evan | not any object. |

| 23:20:14 | benburkert leaves the room. | |
| 23:21:07 | maharg | I think there's a difference between something 'being' a model and 'being capable' of a model. You have to work pretty hard to write a program in a prototype-style in ruby. At least as much work (probably actually quite a lot more) as you have to in order to write something in an OO style in a prototypal language. |
| 23:21:19 | maharg | no primitive clone operation is also problematic. |
| 23:21:43 | maharg | but I agree that a ruby vm should make a good prototype vm |
| 23:25:03 | chopmo leaves the room. | |
| 23:25:36 | evan | any optimizations you apply to a ruby vm end up being pretty much the same ones you'd apply to a prototype based one |
