I've switched to Strawberry Perl on my PC and I just loaded MP3::Tag into it {I used it in old of my old programs}. and I'm greeted with this error

I looked at the code and I can see the problem but it is is a bit baffling

  for my $f (@_) {
    $have{$+}++ if $f =~ /^\??({([^{}]+)}|.)/;
  }

Is fixing this as easy as sticking backslashe in front of the of the open and close braces? The.pm is installed read-only but I can finesse that. Is it dangerous to just edit/hack a .pm in ones /site/lib hierarchy?
