> PyIter_Check() and PySequence_ITEM() macros access directly PyTypeObject members and must be converted to opaque functions: (...) PyIter_Check() and PySequence_ITEM() are declared as functions in the limited C API, but overriden with macros in the CPython C API. I suggest to simply remove the macros to always declare them as functions. See bpo-33738 "PyIndex_Check conflicts with PEP 384" which added the functions. See also Tools/scripts/pep384_macrocheck.py script.

See bpo-33738 "PyIndex_Check conflicts with PEP 384" which added the functions.
