It seems to me that you are missing the point,
but maybe I am missing your point.

The question of whether a set or dict guarantees
some order seems quite different from the question
of whether rerunning an **unchanged program** yields the
**unchanged results**.  The latter question is the question
of replicability.

Again I point out that some sophisticated users
(among which I am not numbering myself) did not
see into the source of this "anomaly".  This
suggests that an explicit warning is warranted.

Cheers,

PS I know ordered dicts are under discussion;
what about ordered sets?
