STINNER Victor added the comment: pyobject_fastcall-2.patch: More complete changes. Sorry, the patch also contains unrelated refactoring! It's a more advanced implementation which tries to reduce the depth of the C backtrace. For example, _PyObject_FastCall() is now inlined manually in _PyObject_FastCallDict(). PyObject_Call() is also rewritten. If the overall approach is validated, I will rewriten the patch differently to limit changes, or push some changes in multiple commits.
