Using default in a switch statement when switching over an enum

Question

What is your procedure when switching over an enum where every enumeration is covered by a case? Ideally you\'d like the code to be future proof, how do you do that?

In addition to the advise to throw an exception, if you use gcc, you can use the -Wswitch-enum (and eventually -Werror=switch-enum) which will add a warning (or an error) if a member of you enum doesn't appear in any case. There may be an equivalent for other compilers but I only use it on gcc.
