This change produces minor speed-up: $ python-other -m perf timeit -s "divmod_ = divmod" "divmod_(1, 1)" --duplicate=1000 --compare-to=../cpython-master/venv/bin/python python: ..................... 64.6 ns +- 4.8 ns python-other: ..................... 59.4 ns +- 3.2 ns Mean +- std dev: [python] 64.6 ns +- 4.8 ns -> [python-other] 59.4 ns +- 3.2 ns: 1.09x faster (-8%)
