Simon Law added the comment: 15125-2.patch applies to the default branch. It makes dest behave the same for positional and optional arguments in terms of name mangling. Also, there is a backward-compatibility path in Namespace to support old-style getattr() access. However, it's not documented as we really don't want people to use it. ---------- Added file: http://bugs.python.org/file27863/15125-2.patch _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue15125> _______________________________________
