moon-child I want to write something like ^, but with map instead of for. Is that possible? 00:20

Voldenet moon-child: ^ that's not map, but it's close to how fprog would solve this (I'm not sure if it's even always guaranteed to work) 12:39
m: sub g($states, $key) { $states{$key} = False }; say reduce( -> (%d, $acc), $_ { my $v = %d<LOOP> ?? (|$acc, $_) !! ($acc); g(%d, <LOOP>); say (%d, $acc, $_); (%d,$v) }, (%(:LOOP), ()), |^5); 12:48

Voldenet output is fairly disgusting as expected

Voldenet in fact, for loop seems like a better solution for this 12:58

[Coke] Was referring to newline addition. 16:20
but yes, having gist vs. str in the mix is also confusing. 16:21
japhb Oh yeah, I guess I was thinking say:put 16:25

aru Hi, i've been looking at raku and ocasionally I'm confused by its syntax and where ceratin things can be used. For example with grep, I'm never sure if I have to do grep({ .something }), or grep(*.something), or grep: { .something } or something else altogether. Is there a rule of thumb for these cases? 17:39
lizmat the rule is that .grep takes a Callable 17:40
{ .something } and *.something are different syntaxes for basically the same tihng
aru are they? I could have sworn there were cases when one worked and the other did not, but maybe I was doing something else wrong 17:41
lizmat also .grep({ ... }) and .grep: { ... } are also just different syntaxes for the same tinkg
well, *.foo is syntactic sugar.... and the syntax to convert an expression with * into a Callable are (intentionally) limited 17:42
aru ok, makes sense, thanks 17:45
and another thing, when it comes to specifying types. Can I express something like "a list of lists of Str*Int pairs"? 17:46
gfldex Type checks happen (mostly) at runtime and you can check for anything you like. 17:53

aru right 18:01

Voldenet aru: this is mostly my personal opinion, but I really prefer the most uniform syntax in raku, so `.grep({ $^x })` which can be used almost everywhere 18:43
`.grep: { }` feels weird to use 18:45
`*.something` is convenient when you chain a lot of methods together 18:49
like `($^d.IO.dir // ()).grep(!*.basename.starts-with('.')).grep(*.d).grep(!*.l)` 18:53
also, WhateverStar has some limitations: 19:00
