Again, please don't confuse class derivation with type derivation.  Class
derivation is only one way to make derived types.  See page 24 ARM for
a number of other ways to make derived types.  Also, it has been pointed 
out to me that now that enums are distinct types, perhaps they too should
be candidates for operator overloading:

"An operator function must either be a member function or take at least one
argument of class type, enum type,  or of a type derived from a class 
or enum type."
