japhb In Rakudo's src/core/Bool.pm, why are prefix:<!> and prefix:<not> defined in terms of *both* nqp::p6bool() and ternary (returning 0 and 1) instead of just ternary (returning Bool::False and Bool::True directly)? 03:00
And is there any performance difference between spelling it Bool::False/Bool::True versus just False/True? 03:03
03:07 dbrx left 03:20 sisar left
sorear japhb: yes, I think 03:38
unless rakudo constant folds it, which it probably should eventually
last I checked, rakudo always compiles Foo::Bar into a runtime hash lookup

masak spooky segfault at a distance. 13:05
you wrote such exquisitely beautiful code that some unrelated code felt jealous and went on strike.
timotimo no segfault in the changed code? sign of smashed stack/heap state?
moritz yes, but I only touched fairly high-level code 13:06
timotimo hm :| 13:07
moritz moritz.faui2k3.org/tmp/pre-post-typ...ions.patch is the patch 13:09
and it segfaults with --target=pir , but not with -c 13:10
so it must be during codegen
but it gets to the return PAST::Var.new(:name('Nil'), :scope('lexical_6model')); 13:11

shinobicl___ the issue is that i want D to be inmmutable. But i don't know how to remove the "is rw" from x and still makeit work
jnthn Good morning :) 14:09
Just droping by for a moment...
moritz: The issue is that find_symbol returns the actual symbol, not a PAST node to look it up.

gfldex shinobicl___: class A { has $!x; }; my $a = A.new(:x(10)); $a.x = 11; 14:15
and you should be careful about anything being inmutable that is not a constant 14:17
shinobicl___ my priority is that it should be inmutable. moritzs suggested that if the base clase is inmutable, i should try to make the derived one inmutable too. 14:19
kmp Hi guys. Could I ask if there are any known Radoku test failures at the moment? I was just having a look around the source, built it and saw that the 01-load test failed for me. 14:21
lumi__ shinobicl___: I think you're meant to write your own submethod BUILD() and not method new 14:22
gfldex kmp: Rakudo as in git pull? 14:24
kmp Yeah. Should I be surprised at a failing test? 14:25

masak gfldex: you can't pass non-public attributes to the default .new 15:11
also, having things be immutable-but-not constant is perfectly fine; the main thing is that the clas upholds an invariant of some sort. 15:13
immutable types can even have hidden moving parts, if it serves them. for caching purposes, for example. 15:14
of course, you should never be able to tell from the outside.

masak moritz: that's just so cool. it prints the code. 17:49
moritz: did you notice, however, that there's a stray space in the beginning of the code string?
moritz masak: it's not stray, but neither is it pretty
it comes verbatimly from the <blorst> rule that is used to parse the text after the PRE 17:50
masak I can see how it occurs. but that's an explanation, not a good reaso... right.
maybe apply a .trim somewhere? 17:51
moritz I think I should, yes 17:52
I also think that I should pass the phaser name to the exception object, and do the PRE -> precondition translation inside the error message, not inside Perl6::World
masak nod. 17:53
masak has been discovering this weekend exactly what can and can't be done in modern webapps without a mouse
as far as I can see, there's no way to sign out of Gmail in Chrome without a mouse.
moritz wow
masak also as far as I can see, there's no way to give a github issue a label, save for pressing Tab 34 times. :) but I'm less sure about that one.
moritz I think I'd use some browser extension like hit-a-hint for mouseless browsing 17:54
arnsholt_ masak: If you're mouseless, an extension like vimium might be in order (if you can install it without a mouse =)
moritz ah yes, vimperator and the likes 17:55
I don't have it installed because my wife wants to use my browser too :-)

moritz I don't really see the use case for multiple POST phasers in the same block, so I can't comment on the desired semantics 21:16
I mean when you write POST foo; POST bar; you can juste write POST foo and bar;
jnthn OK 21:19
