OK, I am doing that now. Thanks! The code shown previously is now:

      if (   boost::python::type_id<af::const_ref<std::size_t> >()
          != boost::python::type_id<af::const_ref<unsigned> >()) {

Well, I spent years considering buggy implementations. I am going to stick to
the boost::python::type_id<> comparisons as long as the Boost.Python registry
does.
