tobs Doc_Holliwood: I did some reading on that question a while ago (because it pops up every now and then). See github.com/taboege/raku-Junction-Guts for how to do it and hopefully the appropriate amount of warnings. I don't know how robust the code is, anyway, and never actually used it so far :P 15:14
15:17 xinming_ left, xinming_ joined
Doc_Holliwood Something like a collapse operator would be useful methinks 15:24
So that my $a = 10|-10; my $b = 90|-90; say $a + $b Ψ 100; ok $a == 10;
lizmat Doc_Holliwood: what would that be ?
Doc_Holliwood ^^
lizmat m: my $a = 10|-10; my $b = 90|-90; say $a + $b 15:25
camelia any(any(100, -80), any(80, -100))
lizmat note that by the time the + is done, there is no sign of + anymore in the junctions 15:26
Doc_Holliwood so?
lizmat so how would it know what $a was ?
if Ψ has a lower precedence than + 15:27
I guess the question is: how would you express Ψ using subs ?
Doc_Holliwood what do mean, no sign of +? 15:28
m: my $a = 10|-10; my $b = 90|-90; say $a + $b; say $a
camelia any(any(100, -80), any(80, -100))
any(10, -10)
Doc_Holliwood $a is unchanged
i mean i can say 15:29
my $a = 10|-10; my $b = 90|-90; say $a + $b ~~ 100
evalable6 True
Doc_Holliwood so, some codepath "knows" that 10 + 90 matches 100 15:30
i want that information
tobs Doc_Holliwood: it's stored in the junction internals. You can get it using nqp, but not otherwise to my knowledge, because junctions are not intended to expose their state. 15:34
15:37 atroxaper left
tobs oh, but if you want to combine junctions by +, you create a new junction that is matched with 100. The expression `$a + $b` in `$a + $b Ψ 100` has no ties to $a nor $b anymore. Collapsing junctions according to a function on them would be much harder to achieve than just listing the states of a Junction in Rakudo. 15:38
but I think Damian Conway once wrote a quantum computation-lookalike module which does this.
Doc_Holliwood: the talk he showed this in is very nice if you haven't seen it. The code has also been made public somehow: www.reddit.com/r/perl6/comments/6p...computing/ 15:42
But there the superposition part of Junctions is reimplemented in a way that allows to keep track of the ingredients to various expressions, so that collapsing one value can propagate the observation to the ingredients. 15:45

AlexDaniel El_Che: it was just the practice
El_Che if so, did rakudo moved to the "release when ready" mode?
(both are fine with me)

uzl[m] Aside from post-circumfix [], is there a similar syntax to Array.new() to create fixed-sized arrays? 17:10
jnthn uzl[m]: Yes, pass the shape named arg 17:12
You got the Array.new(:1shape) bit right, but then threw away the array by copying out of it into @a
Use := instead of = 17:13
That and one other odd char somewhere in the cdoe

lizmat reification-target 20:26
AlexDaniel lizmat: why are we using #rakulang when we can use just #raku? 20:29
python folks don't use #pythonlang, right?
lizmat because you don't have that many snake lovers on Twitter, but you do have a lot of pottery lovers on Twitter 20:30
and since we've been accused of squatting on a name for many years, it seemed wrong to me to start squatting on #raku on Twitter 20:31
AlexDaniel but people will use #raku anyway
so why make it more difficult
there are so few tweets about pottery 20:32
and even those who “accidentally” use #raku already account for like more than half 20:33
or maybe around half
and then we gave up r/raku… which had the last pottery post 1 year 20:34
1 year ago*
lizmat twitter.com/search?q=%23raku&s...amp;f=live
I'd say that's not dead 20:35
AlexDaniel it's not dead
lizmat in any case, I think we've had this discussion a few months ago... 20:36
tadzik twitter.com/martinoneill19/status/...2832269312 hah :) 20:37
AlexDaniel it's just hilarious, we're going through all this trouble to fix the name only to do the wrong thing again and come up with social tags that just won't work 20:38
I guess it would've made sense if we were using rakulang github org and rakulang.org, but we don't 20:39
I mean… I guess it doesn't matter, and everyone will use #raku anyway 20:40
El_Che AlexDaniel: if you think so, why bother reopening the discussion if time will result in what you prefer? 20:41
AlexDaniel still though I don't know why we're making it harder for ourselves so that we have to go and police people to use a different tag
lizmat github.com/Raku/problem-solving/bl...cial-media 20:42
AlexDaniel El_Che: it's just gonna be messy, that's it
lizmat because we decided?
El_Che while raku is shorter, I like that rakulang is specific for the language 20:43
so you don't get mixed content
and no, python is an other case
it was a major language before twitter arrived 20:44
I don't see the document as policing (users will do what they like), but it's good to have a media strategy for the project
if it fails it can be amended, but I think it's way to soon for that 20:45
(I think the #rakulang thing is going as well as it could be expected) 20:46
Grinnz I have three thoughts on the matter: 1) it's good to have and promote an option that will be unambiguous, 2) people can be context aware and "raku" is not ambiguous in other places like it is on twitter, 3) it's not the end of the world when it's used on twitter, since it's not easy to confuse the content of one for the other
lizmat [21:37:06] <tadzik>twitter.com/martinoneill19/status/...2832269312 hah :) 20:47
:-) 20:48
Grinnz with the exception of that one :)
El_Che it looks like genitals to me :)
sjn AlexDaniel: If there's a place (e.g. an issue in the problem-solving repo) where tags are discussed and at the end decided upon, I'd love to hear about it. :) 20:49
El_Che sjn: lizmat linked to it a few paragraphs above
sjn ah, didn't see that 20:50
in that case, I won't return those stickers quite yet :)
El_Che it was a small part of the renaming discussion
sjn mm 20:51
El_Che what's wrong with the stickers?
lizmat they say #rakulang
which was just put into question
sjn El_Che: they're fine. One sticker says #rakulang
El_Che they would be fine either way, but #rakulang is prefered
sjn the others say "Raku"

You can't really use gather/take for your loop, because your exit condition is the size of the array. But `gather`ed arrays don't get update until the gather loop is done. 21:57
this doesnt work at all 21:58

Doc_Holliwood and this is just as ugly, since it requires a counter
