The frame object I am referring to was:
PyFrameObject *frame = PyThreadState_GetFrame(PyThreadState_Get());
This frame can not be used with PyObject_GetAttrString. Is there anyway to get
the PyObject* associated with a PyFrameObject*? It seems weird

I saw the latest Python 3.11 5A release notes on the frame API changes. Do the
