Wow, very nice. I'm going to play around with that one for a bit. I just started learning regex's in depth, so this is a great tool. I have one I constructed as well, which might be useful, if just a simple match test is your aim: 
#!usr/bin/perl

$my_string = "";
$my_regx = "";

 # This program tests regular expressions against a match.

 if ($my_string =~ /$my_regx/x) 

    print "Matched: "  . "\"" .  $&  . "\"" . "\n";       # print matc
+h
    print "Before match: "  . "\"" .  $`  . "\"" .  "\n"; # print data
+ before match
    print "After match: " . "\"" . $' . "\"" . "\n";      # print data
+ after match

}else {
    # do nothing
} # end if
    
  print "Rockstar Programming Inc. All Rights Reserved\n";

So, now I have yours to explore with and maybe my much simpler "matcher" could possibly be of use to you :)
