Cannot modify an immutable List ((a b c))

$a is a scalar container, holds one thing. In this example a Li
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:

""''(){}[]

(" ' ( { [)
> $string0.comb[(0..*-1).grep(* % 2)].say;
(" ' ) } ])
It sounds like you have some inte

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

i rewrote it my way and this works

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 ex
I guess you need something like this:
my ($a, $b) = { @^a[0,2...Inf], @a[1,3...Inf] }.(q<(){}[]>.comb); say $a; say $b
Best regards,

This reminds me of "the comma rule" which I haven't quite internalized yet.
This gets a little closer
map { .[0,2…∞], .[1,3…∞] }, ("012345".comb,)
(((0 2 4) (1 3 5)))
and my instinct is that "map" is adding a layer you don't need or want for
this issue, should just be sending the results of comb
10 matches
