Since Python 2.3 many open-like functions supports "Universal line mode" (PEP 278 [1]). Since 3.0 (and 2.6) PEP 3116 [2] suggests better alternative -- io.TextWrapper. In issue15204 [3] proposed to deprecate "U" mode in open-like functions. In fact I found only three places where "U" mode is mentioned in the standard library: * builtin open (io.open) (almost ignored); * fileinput (transparently passed to open); * zipfile (inefficient and inconsistent implementation). Is someone uses "U" mode and has objections? [1] http://www.python.org/dev/peps/pep-0278/ [2] http://www.python.org/dev/peps/pep-3116/ [3] http://bugs.python.org/issue15204

I'm ok on the principle, I just think we should minimize disruption (I don't think the "U" mode adds a lot of complexity to the code). Regards Antoine. -- Software development and contracting: http://pro.pitrou.net
