I just used __add__ as an example. Of course all (differing) vtables and
methods would need the adjustment depending on the code origin.

Baically yes, albeit C<get_attr> isn't a MMD function. Its a plain
vtable function C<get_attr_str>.

That's similar to or a generalization of 1). It IMHO implies that Python
on Parrot willl not be used much.
