//this is a proof-of-concept-*only* C++ access-privilege elevation exploit.
//this code is 100% legal C++, per C++98 section 14.7.2 paragraph 8:
//"access checking rules do not apply to names in explicit instantiations."
//usage example:

//struct N { typedef void (Class::*)(); };
//template class public_cast<N, &Class::Reference>;
//(class.*public_cast<N>::value);

//Class::Reference may be public, protected or private
//Class::Reference may be a function, object or variable
