Research direction

Start by running the minimal reproducer in superbug.py and compare its behavior with superbug-fixd.py, the uploaded proposed fix. Then locate the corresponding generator-expression and zero-argument super handling in CPython and its tests. Done means the reproducer works correctly without regressing related super() behavior.
