But if there's more than one line ending used, that's not good enough. Universal newlines is a wonderful convenience for most text usage, but if you really need to be able to preserve format, it's not going to be enough. I think it's best for universal newlines to be simple. Let fancy facilities be provided by a library wrapping raw IO, as you suggest. _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
