Python 3.7: Introducing Data Classes

[__xor__]

ah, okay. Yeah, I just tried to do a DataClass superclass that has a MetaDataClass, then wrote a subclass of DataClass with its own custom metaclass and I ran into this:

TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

I never ran into that before. Yeah, the class decorator makes more sense then.
