Is it possible to make it have the following sort of behaviour? :
>>> ShirtSize.small == AppleSize.small
True
>>> ShirtSize.small is AppleSize.small
False
It works for comparing a boolean (True) vs. an integer (1), so it has
some sort of precedent. (Especially if you make the tenuous assumption
that True,False are language-supported 'enums' for 0 and 1.)
