falsifian I think the constraint is elementwise. 00:41

chicken hm when i use is copy on $/ the make doesn't seem to assign the .made in the current scope or something idk ```pl 02:35
grammar Code {
token TOP {
^ [<expression> \n?]* $
}
rule expression {
<number> | <func-line>
}
token func-line {
<[₀₁₂₃₄₅₆₇₈₉]>
}
token number {
\d+
}
}
class Parse {
method TOP($/) {
make $<expression>>>.made

huh and for some reason when i try this ```pl 02:40
method func-line($/ is copy) {
make (0..0).map({
my $res = Code.parse("1", actions => Parse).made;
say "res $res";
$res
});
}
``````
res 1
[([1]) 5]

Nemokosch <@435939911455997952> be warned that unfortunately these messages are sent to an IRC channel as well and the way they show up is probably horrifying 11:23
it's generally a better idea to send anything long with some pastebin kinda service, e.g Github gists 11:24
You might know that $/ is a variable set at all matchings - probably .parse sets it as well 11:29
I think the most straightforward solution is to break free from $/ 11:30
docs.raku.org/routine/make 11:31
once you are doing matchings inside of parsing (which I'm not sure is a good idea in the first place), it's better to specify the parameter with some other name and call .make on that 11:32
