    Is there a way to do this in Perl5? I don't have the qr// thing.

      qr was added in Perl 5.005_03. If you're running anything older than that, you should consider an upgrade, as previous versions are considered buggy. 

      my @regexes = ('HELLO(\w+)', 'hello(\w+)', 'Hello(\w+)');

for my $re (@regexes) {
  $re =~ s!/!\/!; # escape delimiters

  my $eval = '$string =~ /' . $re . '/;';

  if ( eval $eval ) {
    print "$string matches $re\n";
  }
}

      It's an ugly hack, and I would very much prefer it if you would promote world peace, fight hunger and help stop global warming by upgrading your version of Perl.
