I think the idea in Python dir is to allow a type to have methods
and members that are not in the __dict__ and thus cannot be changed
without the type's code getting involved.

In CXX __methods__ lists the functions of the type that
are public. They are not in __dict__ and cannot be damaged
from Python code. CXX does not support __members__ by default.

I wonder if it is possible to remove a function from a py_cpp type
by assigning into the __dict__ from python.
