Research direction

Start by running reproducer.py and reading the inspect.getsource(obj.foo) entry point. Review issue_19956.patch and issue_19956_1.patch to understand the proposed handling, then check the existing inspect tests for suitable regression coverage. Done means the injected method can be inspected without breaking current getsource behavior.
