We actually go through whatever curry on each curryeable thing like a method call or some op. Avoiding the dynvar and caching the lookup of Whatever, WhateverCode, and HyperWhatever in lexical vars comes out about 10x faster.
Makes compilation of 3000-line file ~6% faster. Not a lot but... Whatever

zacts what main features would Perl6 add to OOP if I am coming from Ruby? 02:01
Geth rakudo: 2339d8dd00 | (Zoffix Znet)++ | src/core/Exception.pm
Travis unbusted; restore X::Comp::BeginTime to former glory
skids zacts: Not a ruby person myself, but types are not duck-typed, interfaces (here called "roles") may be parameterized. Probably a lot more but hard to say not knowing ruby. 02:07
Zoffix zacts: I don't know Ruby, but we do have a "from Ruby to Perl 6" guide. Perhaps it mentions something (I see there's "Object Orientation" up in there): docs.perl6.org/language/rb-nutshell 02:07
zacts cool ok 02:07
I'll check it out
is Perl6 OOP based on CLOS? 02:08
Zoffix has no idea, sorry :) 02:09
zacts s'ok :-)
I'll look into it. 02:10
skids reading en.wikipedia.org/wiki/Common_Lisp_Object_System most of those features are available. The MMD may work slightly differently. Inheritance is C3. 02:11
zacts oh so it seems that Perl6 provides PEG parsers. cool.
zacts I'll ahve to try this all out 02:12
Zoffix \o/
skids It can also inline the grammars through a mechnism called "slang" and you can alter the local Perl6 grammar by subclassing it. 02:13
ctilmes What is "Serialization Error: missing static code ref for closure 'run' (gen/moar/stage2/NQPHLL.nqp:1834)" 03:27
Zoffix ctilmes: sounds like an internal compiler error. 03:34
Any chance you got the code that produces it?
Some sort of --profile option? 03:35
--profile-stage
ctilmes I figured it out -- I'll try to make a small example that triggers it. I was re-exporting a bunch of symbols by some I forgot to include my module that exported them. 03:37
ctilmes Zoffix: Put this in a module and 'use' it: "my package EXPORT::DEFAULT {}; BEGIN EXPORT::DEFAULT::{'this'} = ::('this') }" 03:41

camelia bad type on :as
skids So just adding a candidate like that could deliver an error message.
skids but not for .unique method due to interface consistency. 15:45
skids Adding that candidate though might mess up people trying to add a 'unique' multi sub that takes :as(Int). 15:49
So maybe a more generic candidate that takes and looks for unknown/badly typed nameds and warns, but then runs. 15:51

Voldenet What's the preferred way to reduce writing `MyClass.new(:field1($x), $field2($y));` into `MyClass($x, $y);` 16:33
a subroutine, or maybe some more elegant way? 16:34
Voldenet m: class X { has $.n; multi method Str() { "value: $.n" } }; sub X-n ($v) { X.new(:n($v)) }; say ~X-n(42); 16:40
camelia value: 42
Voldenet that's what I came up with, but this doesn't seem very elegant 16:41
Juerd Voldenet: Provide your own BUILD submethod 16:47
Geth doc: 3bf1d5efe2 | (Luca Ferrari)++ | doc/Language/regexes.pod6

Geth doc: 26c5cdd0e8 | (Luca Ferrari)++ | doc/Language/regexes.pod6
Add a section to explain $/ changes each time ~~ is used.

Explained also named captures. See issue #1752
Voldenet Juerd: but doesn't that leave me with .new everywhere?
Juerd Voldenet: I assumed leaving out .new was a mistake. Why would you want to get rid of that?
Voldenet because I'm making large trees and it seemed unwieldy in cases where I'd need to use a lot of them 16:50
geekosaur nobody said your constructor has to be called .new 16:51
Juerd geekosaur: But leaving out the constructor completely, is that even feasible? 16:51
Juerd It looks pythonesque, but I don't see any advantage 16:52
Voldenet it's shorter ;D
geekosaur er? it's in there still, it's hidden inside X-n
but it could be a class method instead. (also, uh, can I suggest you not use X as a class name? the eception namespace *will* bite you at some point)
Juerd Voldenet: If you just want short, use a single-letter subroutine :D 16:53
Maybe an operator even
Voldenet > equation-n(mul-n(sum-n(expr-n('a'), expr-n('b'), expr-n('a'))))
it'd be way more unwieldy if I wrote this with .new everywhere 16:54
not that it's any good, I made some mistakes on the way
but I'm writing tests for some expression reducers, just for fun
Juerd m: class Point { has $.x; has $.y; }; sub infix:<`>($x, $y) { Point.new(:$x, :$y) }; say (42`69).x 16:55
camelia 42
Juerd That's short! :)
Voldenet actually, that is pretty clever 16:56
geekosaur this is starting to look like apl, though >.>
Juerd geekosaur: Well, if someone values brevity over clarity, that's their fate anyway :) 16:57
Voldenet I bet I'll be pretty surprised
later
Juerd Anyhow, to be honest, if I read things like mul-n and sum-n, I think operators would be better anyway.
Voldenet m: class X { has $.n; multi method Str() { "value: $.n" } }; sub prefix:<@> ($v) { X.new(:n($v)) }; say ~@42; 16:58
camelia value: 42
Voldenet Juerd++ for the apl powers ;) 16:59
Juerd Maybe even just define an operator for expr-n and overload existing operators (I mean provide new multi candidates for them) to do the rest
Juerd Voldenet: X is already used by the language for exception stuff, @ is used for array stuff. You may want to pick different characters. 16:59
Most of unicode is still available! :D
Voldenet Watch me when I reimplement + and - operators >.> 17:00
geekosaur this has been a fertile source of weird bugs n the past
even more so if someone actually did some of the things discussed in dev where spesh assumes you did not so overload various things 17:01
Juerd geekosaur: On the other hand, nothing like fuzzing and chaos monkeys to find bugs and harden something
Also, if there's a "just don't do that", it should be documented imho
So it might just be a good way to find those things
geekosaur if that spesh thing ahppened, you will lose that bet; you will have to declare that you are breaking the rules 17:02
Juerd use MONKEY-WAR;?
geekosaur but I don;t think it has as yet, specifically because someone needs to work out how to make it clear that problems await
Juerd use CHAOS-MONKEY;?
geekosaur neither really. monkey wrench :) 17:03
Juerd Nice one 17:03
Voldenet if the problems await, I just have to give them some nice promises
Voldenet m: sub prefix:<.> ($a, $b) { say $a ~ $b }; say "two" . "three" 17:05

Unsupported use of . to concatenate strings; in Perl 6 please use ~
at <tmp>:1
------> 3.> ($a, $b) { say $a ~ $b }; say "two" .7⏏5 "three"
Juerd . is used for method things and special cased in the parser iirc
Note that operators don't have to be a single character 17:06
m: class Point { has $.x; has $.y; }; sub infix:<ook>($x, $y) { Point.new(:$x, :$y) }; say (42 ook 69).x
camelia 42
Voldenet yeah, it's pretty cool when they are a single character though 17:10
