Sets may turn out to be *sorted* if they're implemented with trees, but I don't think the implementation promises that either.

The BTrees implementation definitely does promise the sorting relationship for the results of iteration, which is useful. Python's built-in set types do not make that promise (and they happen to be hash-based). -Fred -- Fred L.
