I assume you're talking about this code (from parsefile):
  if (@suffices) {
    $tail = '';
    foreach $suffix (@suffices) {
      my $pat = ($igncase ? '(?i)' : '') . "($suffix)\$";
      if ($basename =~ s/$pat//s) {
        $taint .= substr($suffix,0,0);
        $tail = $1 . $tail;
      }
    }
  }

It recompiles a regex for every suffix on every call to parsefile. Yuck! This module could use another function that saves a regex to do the suffix checking (in a closure or an object). Or something :-)
