Since the whole "(?:^|(?:This is ........... terms of )?)" is followed
with "?" making it completely optional, I do not see the reason to have
"^" and the other matching.
Why not simply
> + if ($licensetext =~ /[Tt]he Artistic License ([v\d.]+)/) {
If you require one of the matching, the whole "(?:^|(?:This is
........... terms of )?)" should not be followed by "?".
I am confused with this rule.
