Well, this probably isn't even possible to implement but i might aswell ask 
anyway.

Can is_polymorphic take an additional optional template arg that is a type, 
or a type sequence.
Those types, are not considered to make the checked type polymorphic.

Example

struct X : public boost::noncopyable {};
struct xor : public std::binary_function<bool,bool,bool> {};

std::cout << boost::is_polymorphic<X, mpl::vector<boost::noncopyable, ....> 
 >::value << std::endl;
std::cout << boost::is_polymorphic<xor, std::binary_function<bool,bool,bool> 
 >::value << std::end;

output
0
0

This would be of great help.

Thanks,

Ray
