Nick Coghlan added the comment: The scrapy case looks to just be the new metaclass constraint that's already covered in the "Porting to Python 3.6" guide: https://github.com/scrapy/scrapy/pull/2509/files
The ctypes case is more complicated, as its actually *reusing* the same class namespace to define two different classes, which is fundamentally incompatible with the way zero-argument super works. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29270> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
