I usually die when either the error is obviously fatal or is not supposed to happen at all (if it happens then there is a bug in the program).

Otherwise I return a false (0) or undef value. False is nicer to test than undef but it is not always possible as 0 might be a valid returned value.

If undef is also a valid returned value then I am in trouble ;--) I try to code around it though, making it an illegal result.
