A way to tell them apart is the presence of the EnumTag, if it's present, then
the enum is a new type:
enum V1 = 10;
enum { V2 = 20 }
enum Foo { V3 }
void main() {
assert(V1 == 10); // OK
assert(V2 == 20); // OK
assert(Foo.V3 == 0); // ERROR, type mismatch
}

I sometimes find it convenient to just treat those values as integers,
e.g. when reading/writing them with a stream (to a file, to some other
process with SocketStream, ...).
Like
---
int x;
stream.read(x); // btw: this often sucks - why not x = stream.readInt()?
if(x == MyEnum.DIE)
return 0;
else if(x == MyEnum.CALLFOO)
foo(x);
---
or something like that (switch() might be better, but whatever).
Also treating named and unnamed enums differently seems inconsistent to me.
