Perhaps more scalable, but still involving an explicit loop:
>perl -wMstrict -le
"use List::MoreUtils qw(natatime);
use Data::Dumper;
my $s = 'ab123cd456ef789gh';
my $triad = natatime 3, $s =~ m{ (\d) (\d) (\d) }xmsg;
while (my @three = $triad->()) {
print Dumper \@three;
}
"
$VAR1 = [
'1',
'2',
'3'
];
$VAR1 = [
'4',
'5',
'6'
];
$VAR1 = [
'7',
'8',
'9'
];
