It's similar, but I would prefer it if you would get it from the
class' __dict__.  One day I may have a reason not to build a true
Python Method wrapper, and use something else instead; that would
break your code.

You can reach the class' dict very simply via:

   detail::downcast<PyTypeObject>(this->ptr())->tp_dict
