Not really....but the only useful data to result_of in the function pointer
typedef is the return type, while in the case of function-objects the
arguments are potent.
IOW where T is a function-pointer, T describes it completely ; whereas
where T is a function-object, the T(a,b,c) syntax is essential.
Therefore when T is a function-pointer, reference or straight function type
result_of<T>::type would seem to me to be a valid invocation.
