Variables can be declared with the enumeration type, and their storage
requirements are determined accordingly.  But enumerators are just constants.
The constants 5200 and 'x', for example, have type int, even though they can
fit in shorts; but they're just constants and aren't necessarily stored.

If this were the company's opinion, I wouldn't be allowed to post it.
