How exactly does it not work? What exactly is in $1? What output do you expect? Are you aware that the code as-is splits on newline characters, which means that "duplicate items" actually mean "duplicate lines"?

If you want to deduplicate a list, I recommend List::MoreUtils::uniq.

Perl 6 - the future is here, just unevenly distributed
