I happened to have witnessed one of these questions where you're pushing the envelope on IRC. Nobody called you stupid, but they did say: don't do that. The basic problem was the: xy problem.

You asked how to see if a value has been set on in a variable, even if it's undef. Various people tried to think of ways to do that, but many suggested defined, which you had specifically ruled out.

You were wondering how to avoid the "uninitialized value used in concatenation" error, but you didn't ask about that, you asked how to check to see if a variable had a value in it. The answer to the uninitialized value question was defined...

Do you see what I mean?

(I may have you confused with someone else. If so, sorry. I swear the guy on IRC was called exodus too.)
