I found an issue in PEP 590: When inheriting a heap subclass from a vectorcall class that sets .tp_call=PyVectorcall_Call (as recommended), the subclass does not inherit _Py_TPFLAGS_HAVE_VECTORCALL, and thus PyVectorcall_Call does not work for it. Possible solutions come to mind: - Inherit tp_vectorcall_offset more normally but handle setting __call__ specially - Inherit tp_vectorcall_offset (but not _Py_TPFLAGS_HAVE_VECTORCALL) more normally, and make PyVectorcall_Call ignore _Py_TPFLAGS_HAVE_VECTORCALL I'll send a PR for the latter. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36974> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
