Calling an unbound method in C using the Public API

Hi, I am one of the maintainer of the atom library (https://github.com/nucleic/atom ). This library provides low-memory footprint Python objects, descriptors and containers enforcing type validation, implements the observer pattern. For list, we basically subc
