To be honest - I don't know if it makes a measurable difference. However, the code is there, it's required for all currently released CPython versions (i.e. those still being supported for years to come), and it is used in seriously performance critical places, such as each generator/coroutine iteration - twice. Why should we add overhead to those without need? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13897> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
