glion is pondering his first #perl6 question 03:49
Hi everyone! 03:50
say i wanted to use only one perl6 feature, the new sigil rules
are there ast transform tools to do that now? 03:51
i.e. perl5 w/perl6 sigils -> ast -> perl5 ast -> for executing as regular perl5 03:52
Tene Hi! 04:00
There's a Perl 5 source filter.

12:39 pkeane left 12:41 renormalist left
fglock I wonder if [particle] implemented END 12:42
I'm investigating BEGIN
in kp6 we have two scenarios 12:45
either detect side effects immediately when BEGIN finishes running, 12:46
or "dump" the whole environment when the compiler emits code 12:47
12:56 ebassi joined
fglock I'm looking for BEGIN examples in the synopsis, 13:00
I don't see examples where BEGIN side effects need to be recorded
BEGIN { COMPILING::<$?FOO> = 42 } # this can be special cased 13:01
$.r = BEGIN { rand } # this can be handled just like "return" 13:02

fglock [particle]: i've just seen it :) 14:12
[particle]: I think I can workaround the kp6-parrot problems with VAR(), 14:14
but i'm still wondering about BEGIN
[particle] yes, i see that :) 14:15
14:15 jhorwitz joined
fglock it's possible to rewrite kp6 to use plain tables instead of Env, but i'm not sure we should go that route 14:15
pmurias fglock: Env is? 14:17
fglock pmurias: the closure structure that Pad points to
which makes possible to run BEGIN blocks 14:18
pmurias fglock: thanks 14:19
fglock: "plain tables" you mean not using the perl5 lexicals, but emulating them ourself? 14:24
fglock no, just keep a table of lexicals, without creating a compile-time representation 14:25
which means, you forbid BEGIN
hmm - i don't like that 14:26
let's see it the other way out:
does it make sense to rewrite kp6 using perl6?
[particle] then you need to wait for perl6 to have BEGIN 14:27
pmurias [particle]: you should use onion as the project name ')
s/')/;)
i always get confused by perl6 vs Perl 6 14:28
[particle] for perl6? yeah, i like that
pmurias [particle]: you like onion? 14:29
as a name
fglock looking at the perl6 roadmap 14:30
[particle] yes, i've always liked onion. i don't know why we haven't used it 14:32

fglock hey, I don't need perl6 to have BEGIN - I need perl6 to have eval() 14:38
in order to implement BEGIN in Perl6-in-Perl6 14:39
unless there is an alternate way
pugs_svn r19227 | pmurias++ | [kp6-perl5] an experimental emitter which attemts to use caching, a bit more work on caching 14:44
pmurias fglock: a method can be a Method or a Code instance or a perl5 CODE? 14:52
s:1st/or/,/
fglock a method should always be a Method, but the kp6-perl5 MOP accepts anything 14:53
pugs_svn r19228 | pmurias++ | [kp6-perl5] fixed a small error 14:54
pmurias fglock: Code objects are passed to add_method by kp6 itself 14:55

hoelzro nope
manne what about .HOW.methods?
hoelzro I can do it in Perl5 easily enough =P
16:21 pbuetow left, Psyche^ joined
hoelzro I think that worked 16:21
