I think the logic breaks down with multiple inheritance. If you make C(A, B), then you can say C > A and C > B, but then you can't say A > B or A < B which breaks sorting.
If you want to know if a B inherits from Base, then I think `Base in B.mro()` will cover that just as succinctly. And if you need to know position you can compare indexes into the MRO.
