On second thought, I don't think there's enough here to warrant putting this in the standard library. E.g. the example from BaseSet actually strikes me as indirect: because <= is the natural operation to provide for sets, hanging everything off lt looks forced.

Agreed.

How about the MappingMixin and SequenceMixin? These both provide much more meat and have more natural attach points (getitem, setitem, delitem).
