True, but in Python, subclassing is usually done to reuse implementation.
Interface subclassing is usually from a common abstract ba

Yes, ordereddict is a dict that maintains insertion order. Stabledict
is probably a dict that maintains _an_ order, so that repr() and the
like return the same value when used on d

Does it need to be a sequential visit of *all* elemen
I don't see a focused discussion of computational complexity of a
sorted dict; its API cannot be simpler than sorting a dictionary and
it has issues and complications that have already been discussed
without completely satisfactory solutions, so the only possible reason
to adopt a sorted dict is th
