I need to think though how __eq__ and __ne__ work, as well as the 
ordering operators.

My specific concern with __ne__ is that there's one flag to control 
their generation, but python will use "not __eq__" if you don't provide 
__ne__. I need to think through what happens if the user only provides 
__eq__: does dataclasses do nothing, does it add __ne__, and how does 
this interact with a base class that does provide __ne__.
