New submission from Terry J. Reedy <tjre...@udel.edu>: In response to a discussion of a patch removing 'useless' post-increments, (which issue has apparently come up before) Guido posted "> Sorry to butt in here, but I agree with Eric that it was better > before. There is a common idiom, *pointer++ =<something>, and > whenever you see that you know that you are appending something to an > output buffer. Perhaps the most important idea here is that this > maintains the *invariant* "pointer points just after the last thing in > the buffer". Always maintaining the invariant is better than trying to > micro-optimize things so as to avoid updating dead values. The > compiler is better at that."
A condensed version of the above added to PEP 7 would help new developers see the usage as local idiom rather than style bug. ---------- assignee: docs@python components: Documentation messages: 136991 nosy: docs@python, terry.reedy priority: normal severity: normal status: open title: PEP 7, C style: add ++ policy and explanation _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12188> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
