Hm. Maybe for the ordering comparisons we could defer to the class

use C.__gt__. Which had better not reject this on the basis that other
is not an instance of a subclass of C.
IIRC there's already something in the interpreter that tries the most
derived class first for binary operators -- that may force our hand here.
I'm leaning toward doing the same thing attrs does. They have much more
experience with this.
Except that given Hynek's response in
https://github.com/ericvsmith/dataclasses/issues/51#issuecomment-347769322,
I'm just going to leave it as-is, with a strict type requirement for all
6 methods.
