Sure, you could do whatever you wanted, really. Personally I like to die when something seems like an obviously fatal error. That doesn't mean that your *program* will die, because you can catch the die in an eval block. Which is what I do.

Well, no; the die just *dies*. Your sub won't return at all. Your program will die, unless you have an eval block, in which case the die will shoot you out to the closest eval block, and will populate $@ with the error message. And then you said: 
    > But this could cause
    > errors if not handled in the main clause, right?

Certainly. That's why the errors should be handled. :)

Instead of dying, then, you could have your sub return a false value. That would work. Then you could do your checking out in the caller. Some people find that preferable, I'm sure, and that's fine; my preference is to throw exceptions as soon as something bad happens. Then I catch them.
