- Where should PartiallyOrdered and TotallyOrdered live?

Could someone please post some sample code using either of these? I don't see what they're good for.

Here's my failed attempt:

def my_max(a : TotallyOrdered, b : TotallyOrdered): return a if a >= b else b

But this is both too loose (consider my_max(7, "spam")) and too strict (consider my_max([1, 2], [2, 1])).
