Description
Bug Description
getattr cannot be accessed via the type's getattr slot0 wrapper.. Accessing getattr in this manner is possible for a class defined in pure Python.
Steps to Reproduce
Adding the following test to test_getattr in test_proto_methods.rs, leads to an AttributeError instead of a TypeError
py_expect_exception!(
py,
example_py,
"type(example_py).__getattr__(object(), 'test')",
PyTypeError
);

Research direction
Start with test_getattr in test_proto_methods.rs and run the existing test to reproduce the AttributeError. Compare the type(example_py).getattr behavior with the expected PyTypeError for a pure-Python class, then confirm the test passes with the corrected slot access behavior.
