guifa but plz don't do that because line noise ha
Nemokosch the following code just downright segfaults for me 01:16
m: given x => 1, y => 2 { when (my :(:$x, :$y) := $_) { say 'BLAH' } }

Nemokosch (v2022.02 didn't support the syntax yet) 01:17
m: given x => 1, y => 2 { when (my (:$x, :$y) := $_) { say 'BLAH' } }
Raku eval
Nemokosch and this probably does explode for the evalbot as well, couldn't tell by this output xd 01:18
m: given x => 1, y => 2, z => 3 { when my $x := 2 { say 'HMMM' } say $x + $x; } 01:23
Raku eval 4
Nemokosch I'd think this is a bug - why does the when not succeed? 01:24
runs with if
oh right, smartmatching... probably it smartmatches the value of this expression 01:25

Nemokosch gotcha

Nemokosch this breaks my mind, though

MasterDuke huh, can repro the segfault. that's a definite bug 01:35

Nemokosch by the way, heredoc strings are a nice quality-of-life micro-feature 11:09
from what I see, there is something like this in PHP as well but it seems somwhat more awkward

el heredoc nowdoc 11:34
11:57 ab5tract joined 11:59 grondilu joined 12:00 reportable6 left 12:02 reportable6 joined
moritz isn't not really a micro-feature, in the sense that it does make the parser significantly more complicated 12:21
Nemokosch on the other hand it has no runtime impact 12:26
Voldenet heredocs that support tab/space trimming gets it even more complicated 12:28
the syntax in PHP is straight out of perl btw
C# needed 11 versions to get proper heredocs (they called it raw string literals) 12:31
Nemokosch > C# 11 Preview Updates – Raw string literals, UTF-8 and more! 12:33
it seems not only that took them 11 versions...
Voldenet that utf-8 is a not useless, but it's made to win at some benchmarks… 12:35
Nemokosch also, very bluntly put, Raku sacrificed quite a lot of parsing benefits with this approach where you can basically switch to a different sub-language by any token 12:36
so just as much it's good to see the beneficial part of that trade-off, well, any trade-off should have benefits, right?
Voldenet _should_ 12:39
Nemokosch tbh I think these things should also get some showtime. "So you say Raku's grammar is complex and it's hard to inform the user where a certain syntax error could happen? In return, you get a decent remedy to a challenge that gives everybody a headache in pretty much all languages" 12:40

el - complex grammar - no backtracking parser 14:14
Nemokosch this was mentioned not so long ago - actually the latter is decided by the former 14:15
if you want to allow "deviations" (like switching to a slang at any point and then back), backtracking will be too much.... 14:16
14:16 jgaz joined
the amount of ambiguities and their processing, that does sound like a dangerous road to walk down on 14:17
el so the grammar is too complex for backtracking 14:19

shmup haha moritz , i'm so new here i really cannot complain at all! 15:03
i was just waking up, checking irc from mobile, and screaming at columns
proof!!! heh cdn.discordapp.com/attachments/103...G_2742.jpg
it's possible discord is an avilable nick on freenode heh 15:13
lizmat who cares ?
shmup well for starters i absolutely meant to say libera :3 additionally you're right probably, who cares 15:16
lizmat heh, ok :-) 15:18
jdv esp. since on the logs site that is stripped:) 15:21
shmup haha, yes, i should def be controlling this myself. it's a complaint from the PEBCAC section. irssi is good at controllin this sorta thing 15:22
