If the error is really unexpected, don't be afraid to croak or die. eval/die is comparable to try/throw in other languages. If the error is expected to occur, then undef is probably the best returned value.

Personally, I think "return undef;" is more clear to the reader than "return;" even though they have an identical effect. Explicitly returning undef tells the reader that hey, dammit, the caller is probably watching for a false/undef return.
