If to Carp is wrong, I don't want to be right. But you don't use them because they're "a little better", but because they're "the right tool for the job". Using croak or carp reports the error itself in much the same way as die or warn would, but they point the finger of blame at your module's caller. That is to say, if my code calls a subroutine in your module, and your subroutine in turn calls croak, then the error message is going to identify the bug as having occurred in MY code, instead of yours. The line number and file name report where I called your code. (See the Carp docs for the full story.) So, if you're trying to say, "you've misused my module", then carp and croak are the way to do it. If, on the other hand, you're trying to say, "something unexpected happened, and my code wasn't prepared to deal with it", perhaps warn and die will be more appropriate. It all depends, in the end, upon how you can best assist the person who will be unfortunate enough to see the error message.
