Georg Brandl <ge...@python.org> added the comment: It's defined that way because it's a slot returning a bool, so it doesn't need to return anything except for 0 or 1.
Changing this to return a PyObject would mean that every extension module (i.e. module written in C) that defines a custom __contains__ would need to be adapted. That is the non-trivial implementation that Benjamin was talking about. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13667> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
