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.

Maybe this could go into the Demo directory or in some example or HOWTO.

We'll revise this issue when we are going to introduce a standard type or interface hierarchy (not for Python 2.3).
