is_enum?

Just browsing composite_traits.hpp and is_enum.  My compiler (Metrowerks) 
doesn't support is_convertible (at least I don't  think it will, haven't 
actually tried).  But I was wondering if the following class might 
mistakenly be classified as an enum?

struct NotAnEnum
{
     operator int() const {return 0;}
};
