Re: Returning undef: The point I would like Damian to reconsider

I think "The One Rule" is that you must clearly document the return values of your methods or subroutines and expect the users to read the docs.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
