Should we have a function to determine if a class is polymorphic? I guess
it would be in type_traits. Here's a sample implementation I saw in an
Usenet message:
> template<class T> bool is_polymorphic()
> {
> bool result = false;
> typeid(result = true, T());
> return result;
> }
I think this version is for compilers that need assistance from function
arguments for determining template parameters.
