It's good if you can cover all enum values, which usually you can't.
enum according to the standard should be located in the type that is
enough to keep it and be compatible to a char. This means that the
code somewhere else may assign anything to enum (actually enum values
are type of int) and without default you can't see the difference here
and the compiler probably will be happy. That said, I doubt the
usefulness of such a warning. But it's up to you.
