Defensive code is the difference between fragility and robustness.

    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';?
