Hi All,
I narrowed it down by processor eli8mination.
The offending line is
if $Code { $RtnCode = $proc.status; }
I presume what is depreciated is `$proc.status`
Sigils mean a lot. For example, they create a context:
my $a = 1,2,3;
my @a = 1,2,3;
$a = ; say $a.raku;
@a = ; say @a.raku;
If you have some (actually, a lot of) spare time you can watch my class from
TRC2021 where I cover a lot about symbols/sigils/object interaction in Raku:
Hi Marc!
Is it just even/odd elements that you want to separate out? If so, maybe
.grep() is your friend here:
> my $string0 = q!""''(){}[]!
""''(){}[]
> $string0.comb[(0..*-1).grep(* %% 2)].say;
(" ' ( { [)
> $string0.comb[(0..*-1).grep(* % 2)].say;
(" ' ) } ])
It sounds like you have some
"How would you know what types are compatible for a particular operation?"
Operations are functions so the question is the same as "How would you know
what types are compatible for a particular function"
which gets to inspecting a routine's arguments. This SO page helped me
figure that out

I think it's possible to avoid the

With this and what i understood from Vladim, i
thanks everyone for sharing,
Vadim,
my ($a, $b) = { @^a[0,2...Inf], @a[1,3...Inf] }.(q<(){}[]>.comb); say $a[0];
say $b[0]
oh. i never see this direct call of a lambda before but it really makes
sense! this is the answer i like the most.
i rewrote it my way and this works
my ($a, $b) = {
Hi Marc (and yary)!
I'll give this a shot, focusing on bracket pairs. It's not clear from your
question whether there's any inherent order to the bracket characters in
your string, or whether-or-not some might be nested within each other. You
show a lone ampersand ("&") at the beginning of your
10 matches
