my $input = "abcrd-12.3.4";
my $letters = $input.comb(/<[a..z]>/);
my $numbers = $input.comb(/<[a..z 0..9 .]>/);
say "the string $input has $letters letters and $numbers numbers and
periods.";
Just a note, I had to add a "+" to those assignments
my $letters = +$input.comb(/<[a..z]>/);
my $numbers = +$input.comb(/<[a..z 0..9 .]>/);
or otherwise I got a string of the "combed" chars:
the string abcrd-12.3.4 has a b c r d letters and a b c r d 1 2 . 3 . 4
numbers and periods.
