Capture

but it can be used in other ways as well using parentheses around parts of the regex will capture those parts:

use v6;

my $phone = "054-1234567";

if $phone ~~ m/ (\d+) \- (\d+) / {
	say "prefix: $/[0]";
	say "number:  $/[1]";
	say "full match: $/";
}

the matches are also available as $0, $1, ...
