Re: Need help with a match

You have two problems: (1) matches start from 0, not 1. (2) .* gobbles as much as possible (this is also true in Perl 5) so it matches to the ) at the end of (Sub|63218616). As in Perl 5, you add a ? to make it take the shortest match instead: #!/usr/bin/perl6 my $x='sub Test () {
