The only difference between them is "const". However, when I compile with clang-4.0, the second (const) line passes. However, the first one fails! I refuse to believe it's a clang glitch. It must be me doing something really stupid. Help?!
This is to detect a member 'impl_ptr_type' type? Just: template<class, class = void> struct has_impl_ptr_type : boost::false_type { }; template<class T> struct has_impl_ptr_type<T, boost::void_t<typename T::impl_ptr_type> > : boost::true_type { }; Glen
