Stefan Behnel added the comment: LGTM, can't see a case where this might go wrong (errors and type checks are handled before the added code).
It also seems a sufficiently common case to optimise it internally. The 2**n spelling is easier to read and to get right than the shifting, so it's good to make both similarly fast to remove an excuse for micro optimisations in Python code. ---------- nosy: +scoder _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21420> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
