Terry J. Reedy <tjreedy@udel.edu> added the comment: I think that the warning that things are not always as they seem should be repeated in the front of the library manual where the pseudo-arg names are actual used, so the library manual stands on its own. In any case, I believe a lot of people use the lib ref without reading and remembering every detail of the language ref. ---------- nosy: +terry.reedy versions: -Python 2.6 _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue8350> _______________________________________
