An "uninitialised value" warning means that you tried to get data out of a variable that you hadn't put any data into. That sounds like a bug to me. Sure, it might be a pretty harmless bug and, yes, Perl will almost certainly do the right thing when faced with that situation, but it's still a bug.

How hard would it be to fix the bug in your code? To make sure that variables that you try to get data out of have always got data in them - even if it's just an empty string.

Personally I'd make the effort and fix the bugs. But it's your code and it's up to you (or your manager) what you do in this situation. If you want to just ignore these bugs, then you might find no warnings 'uninitialised' to be useful to you. I don't recommend it, but the functionality is there.
