It makes perfect sense if you think of an enum as an integral

I do not wish to think of enums in this way. Your use-case is
better solved with Typedef and a struct.
Me neither. An enumeration should exactly do this: enumerate each
of it's possible values. If you like to do arithmetics on it,
it's something different. Especially flags and colors are NOT
enumerated - you give only some names for some edge cases. So why
not call it such: "named examples" and make it a differnt type,
where arithmetic is allowed and "final switch" is not (like for
int)?
Especially this is what is really annoing, and a "default" case
is not even allowed in a final switch - so it should also not be
possible to construct illegal values other than by explicit
unsave operations (like cast).
