I think it's time that either your co-worker or perhaps all your co-workers who have to maintain your or anyone else's Perl code check in to their local community college and take a refresher course and LEARN about some of these things.

When I was learning Perl, HoH's were in the second half of the course I took, but just by reading the camel book I was able to at least figure out how the HoH worked.

At what point did people become so afraid of books that they are unwilling to at least try to learn?

There is no emoticon for what I'm feeling now.
