PyLong_Check is two memory reads, bits operation, and comparison with 0. And one non-inlined function call when limited API is used. PyLong_CheckExact is only one memory read and comparison. I am not sure that the difference is significant enough to justify the optimization. I would require evidences that this optimization is significant if it would be proposed now. But the code is already written in such form, and I am not sure that it is worth to spend our time to change it. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43267> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
