This program compiles and runs with no errors:


void main(string[] args) {
    final switch (args.length) {
        case 0: break;
    }
}


But in such cases I suggest the compiler to statically refuse this code, and
give an error.

See also bug 5713 and bug 5714

Note this bug is different from 5713 because in 5713 I don't like an error
message (and I'd like the compiler to enforce the presence of the cases for
0,1, and 2), while in this case I'd like an error message.
