New submission from Nick Coghlan <ncogh...@gmail.com>: As noted in https://docs.python.org/3/reference/datamodel.html?#creating-the-class-object, implementing PEP 487 required the introduction of __classcell__ as a way for __build_class__ to pass the zero-arg super() cell object through to type.__new__.
Now that Python 3.7+ offers context variables, we may be able to design a more robust (and better hidden) alternative which stashes the "current zero-arg super cell object" in a context variable, allowing type.__new__ to retrieve it when needed, without having to pass it through the class body execution namespace. ---------- messages: 314650 nosy: Martin.Teichmann, encukou, ncoghlan, yselivanov priority: normal severity: normal status: open title: Investigate using a context variable for zero-arg super initialisation type: enhancement versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33179> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
