Thanks Williams!

Yes, 'required', 'minlength' and 'maxlength' are all more meaningful than the ones I'm using. Will use yours definitely.

I'm not so certain about how to change the catching bad characters part from your input on regex. That is, 

  if ($checks{'data'} =~ /([^$checks{'regex'}])/) {
    bail_out("Bad input.");
  }

Would appreciate a little more advice :)

update

You mean liks this? 

  my $default = '-\@\w. ';
  $checks{'charclass'} ||= $default;
  my $re = qr/$checks{'charclass'}/is;

   if ($checks{'data'} =~ /[^$re]/) {
      bail_out("Bad data");
   }
