Why can't an enum value be fully qualified in a switch statement?

Question

(note: edited question; the prior intent was not clear)

Consider this code:

public final class Foo
{
    private enum X
    {
        VALUE1, VALUE2
         


        

Answer 1

SwitchLabel expects an EnumConstantName, which is defined as the enum constant identifier, which is unqualified:

EnumConstant:
Annotations_opt Identifier Arguments_opt ClassBody_opt
