May I take that as meaning you just jumped to the conclusion that extending polymorphism is useful on no actual evidence of usefulness? > but as long as bytes paths are supported polymorphicly all over the > stdlib, we won't get rid of supporting bytes paths. So are you > proposing to deprecate bytes paths? You claim "almost always want str", Ethan claims "bias against bytes." Sorry, guys, you can't have it both ways. Either bytes paths are discouraged (not "deprecated", not yet), or they aren't. I say, let's not encourage them. Ie, keep the status quo for bytes, and make things better for the preferred str. Yes, that means discouraging bytes relative to str in this context. That's a Python 3 principle, one strong enough to justify the huge compatibility break involved in making str be Unicode. That compatibility break has been extremely successful in my personal experience as a sometime Python teacher and Mailman developer, though the Mercurial developers have a different POV. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
