10:25:31yglukhovcan't really remember you telling me anything like that :(
10:26:14Araqwell it's a good thing we keep delaying the release ...
10:26:34Araqlots of bugfixes + immediate release doesn't work.
10:26:59yglukhovis 3343 hard to fix?

10:30:51yglukhovhmm.. how is that related to pointer+deref+asgn
10:31:07Araqit's a fake prototype for better metaprogramming
10:31:54yglukhovah ok
10:32:02Araqin a generic context we rewrite a[i] = x to `[]=`(a, i, x) only to rewrite it back to a[i] = x for the builtin array/pointer access
10:32:14Araqit's a big mess
10:32:29Araqbut fixes a couple of glitches
10:32:50Araqone showstopper bug left :-)
10:37:22yglukhovwhich exactly `[]=` are you talking about? there's a few of them
10:37:53yglukhovoh, nevermind, didnt see your commit
10:46:12veganskAraq, what version the upcoming release will have?
10:50:32*vendethiel joined #nim
10:51:34wuehlmausvegansk: no 1.0 if you are thinking about that.

11:22:49Noob____Does anyone here know how to use multidimensional access on a custom class? I'm trying to write a proc that will allow me to use the following : <data>[i][j][k]
11:24:48dom96Something like:
11:25:21dom96proc `[]`(data: MyType, index: int): MyItem
11:25:31dom96proc `[]`(data: MyItem, index: int): MySubItem
11:25:43dom96proc `[]`(data: MySubItem, index: int): MySubSubItem
11:25:45dom96Perhaps?
11:26:05Noob____Yea i think that will work
11:26:11Noob____I was hoping it'd be simpler
11:26:30Noob____Thanks
11:26:42dom96Noob____: what were you hoping it would be like?
11:27:18veganskOops. Last devel is broken on my project: SIGSEGV: Illegal storage access. (Attempt to read from nil?)
11:28:44Noob____I was hoping you'd just be able to overload it, `[][][]`(i,j,k: int)
11:29:41softiniogokr: Congrats! Just up voted you on hacker news!
11:29:52gokrhehe thanks :)
11:30:09gokrI didn't expect this amount of interest. But its fun.
11:30:24dom96Noob____: You might be able to get data[i,j,k] syntax working
11:30:38dom96via proc `[]`(data: MyType, i, j, k: int): MyItem
11:32:48Noob____Yea
11:32:49Noob____that works fine
11:32:57veganskAnd it's about unittest again :-(
11:33:56dom96yeah, unittest is quite a complex beast

11:47:31dom96Arrrrrrr: oh, guess that's my bad.
11:48:21dom96For ipv6 support it's required :\

17:34:03AraqJehan_: any opinion on scope based vs function based closures? (dunno if there is standard terminology for it)
17:34:20Jehan_Araq: What do you mean by that?
17:34:42Araqwether a new closure is allocated per loop iteration or not
17:35:06Jehan_Araq: Heh. That's actually a pretty tricky piece of semantics.
17:35:21Jehan_It's a problem that functional languages (mostly) don't have.
17:35:33Jehan_Also, binding of variables.
17:35:56*pregressive joined #nim
17:36:05Araqthe workarounds are well known and our current solution is a pain in the ass to maintain
17:36:25Araqso I'd prefer to switch to function based closures
17:36:34*pregressive quit (Remote host closed the connection)
17:36:37Jehan_Hmm. What is the current solution? I must admit I find myself using templates more often where I'd use closures in other languages.
17:36:50*pregressive joined #nim
17:37:02Araqthe current solution allocates a fresh environment per loop iteration

17:37:50Jehan_Yeah.
17:37:58*Demos joined #nim
17:38:14Jehan_Things tend to get really problematic when you have mutable state and don't do that.
17:38:39Jehan_I think C# even had to change the precise semantics for that a while ago.
17:38:59Araqexactly but C# went from function based to scope based
17:39:01Jehan_Basically, you want to create one instance per function invocation, right?
17:39:07Araqright
17:39:41Araqalso might make async faster
17:40:24Jehan_How about making it an option?
17:40:56Araqthat makes it even harder to get correct
17:41:20Araqthe workarounds are well known anyway since JavaScript is function based
17:41:41Araqand indeed it would improve JS interop too
17:42:05Jehan_Ugh. The problem is that both have their uses.
