FWIW, the techniques for managing parameter passing are covered in this blog post: https://rhettinger.wordpress.com/2011/05/26/super-considered-super/ ---------- nosy: +rhettinger resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38262> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
