You are correct, I was thinking of where I use delete($input) || '' to ensure a defined value and "0" is not a concern. The second form you present (using ?:) is more correct in the general case.

As for using an "ancient version of Perl" I don't have a choice at $work, we are stuck on 5.8.9 for at least a few more months.

You must always remember that the primary goal is to drain the swamp even when you are hip-deep in alligators.
