That last comment is very interesting to me... I think it would be good 
if the enum implementation doesn't prevent the creation of a subclass of 
integer enumerations which can be extended so that when arithmetic is 
done on them, that new enumeration values and names can be added to the 
collection (think flag fields). The add ones might have names that do 
not follow the rules for identifiers.
