in thread Debugging "Use of uninitialized value" warnings.

Agreed. I generally try to code defensively, but in the context of my original question, I am trying to make the defensive code implicit (Perl automatically tells me when and where I used an uninitialized variable) rather than explicit (adding code to check if a variable is unitialized then dying/warning if it is).

Both have the same result, but I think the former results in cleaner code.

    It'd be a handy feature to have, certainly, but I'm not aware of any easy way to get it. If there were a pragma to turn on verbose warnings of that kind, I'd have a new love.

    My wife might not like it, though, because I'd spend all of my days and nights just gazing lovingly at perl...

      You mean no warnings 'uninitialized';?
        Not at all. I mean more like use warnings 'verbose', if it existed, so that instead of use of uninitialized... we'd get $foo is uninitialized in... at line 42.

[pryrt]: Those others were definitely offensive or unequivocably rude, I agree.
[choroba]: (well, it comes from the 14th century, so labelling it as "modern" doesn't seem appropriate)
[Your Mother]: "They" is becoming accepted but it irritates me sometimes. I tend to just pick she or he randomly or try to use "one."
