No more so than __radd__ - I didn't actually mean this as a serious suggestion, but but python *does* already have multiple dispatch. > > On Mon, Apr 11, 2016, at 17:43, Sven R.

I don't see why you need os.open. Because I'm passing it to modfoo.dosomethingwithafile() which takes a filename and passes it to shutils, which passes it to builtin open, which passes it to os.open. Should Path grow a dosomethingwithmodfoo method? _______________________________________________ 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
