I'm fairly resigned to the fact that I'm going to need some kind of micro-benchmark to compare the different approaches. For example, the bytes based approach has a lot of extra assignments to local variables that the str based approach doesn't need. The first step is to actually have a str-based patch to compare to the existing bytes based patch. If the code ends up significantly clearer (as I expect it will), we can probably sacrifice a certain amount of speed for that benefit. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9873> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
