Sigils mean a lot. For example, they create a context: my $a = 1,2,3; my @a = 1,2,3; $a = <a b c>; say $a.raku; @a = <a b c>; say @a.raku;
If you have some (actually, a lot of) spare time you can watch my class from TRC2021 where I cover a lot about symbols/sigils/object interaction in Raku: https://conf.raku.org/talk/154 <https://conf.raku.org/talk/154> https://conf.raku.org/talk/163 <https://conf.raku.org/talk/163> Best regards, Vadim Belman > On Aug 22, 2021, at 8:57 AM, Marc Chantreux <e...@phear.org> wrote: > > thanks everyone for sharing, > > Vadim, > > my ($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, $b) = { .[0,2…∞], .[1,3…∞] }.(q<AABBCCDD>.comb); > > it would be nice if this one will: > > my ($a, $b) = { .[0,2…∞], .[1,3…∞] }.: q<AABBCCDD>.comb; > > But here is one of the reasons i'm still unconfortable with raku is the > fact that sigils don't make sense anymore to me (in the contrary of perl > were sigils means "i want a [$%@] from this"). > > so as i can't get grid of sigils in this case > > my (\a, \b) = { .[0,2…∞], .[1,3…∞] }.(q<AABBCCDD>.comb); > > i need to choose a sigil.
