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).
