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.

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
