With this and what i understood from Vladim, i tried this
my ($a,$b) = "AaBbCcDd".comb.map: { .[0,2…*], .[1,3…*] };
say $a;
it failed too. Also: the Vladim example of a direct call of the lambda
seems intellectually closer to the problem to me. i realized that the
perl map and for with scalars are work arounds. raku has with.
so i tried:
my ($a,$b) = .[0,2…*], .[1,3…*] with "AaBbCcDd".comb;
say $a
which is exactly the way i want to write things :)
