Perhaps this would be better as something like the following:

template<class T> class type_traits {
    enum { can_memmove = true };
};

class type_traits<foo> {
    enum { can_memmove = false };
};

etc.

That way you get the answer to can_memmove at compile time. Not only
does this save you code (both time and space) but it allows you to
do things which require compile-time constants, such as using
type_traits<T>::can_memmove as a parameter to some other template.
