Even if the compiler has validated that all enum constants have case statements in a switch, it is not safe to omit a default: case statement. When assigning a value to a variable / struct field that is defined with an enum type, nothing prevents an invalid value being assigned. So defensive code must assume existance of invalid values and
s/existance/existence/ Jan
thus all switches should have a default: case.
