Replace code that directly accesses PyASCIIObject.hash with PyUnstable_Unicode_GET_CACHED_HASH(). Remove redundant "assert(PyUnicode_Check(op))" from PyUnstable_Unicode_GET_CACHED_HASH(), _PyASCIIObject_CAST() already implements the check.
The Python C API ================ The C API is divided into these sections: 1. ``Include/``: Limited API 2. ``Include/cpython/``: CPython implementation details 3. ``Include/cpython/``, names with the ``PyUnstable_`` prefix: API that can change between minor releases 4. ``Include/internal/``, and any name with ``_`` prefix: The internal API Information on changing the C API is available `in the developer guide`_ .. _in the developer guide: https://devguide.python.org/c-api/
