This is to detect a member 'impl_ptr_type' type? Just:

template struct has_impl_ptr_type : boost::false_type { }; template<class T> struct has_impl_ptr_type : boost::true_type { };

That *is* a nicer way to do it. Requires a minimum of Boost 1.64 or C++17, though. (Or VS2015, apparently.)

Yes, I liked it too. :-) Thanks, Glen.
