Because Set.t is an ordered container,
and order matters for folds if the operator being folded
isn't associative.
These functions are deterministic and depend on order:
Set.min_elt, Set.max_elt, Set.elements, Set.fold, Set.iter
Set.choose, however, chooses at random, and Set.for_all
doesn't appear to be ordered either (is that a bug
in the doc or deliberate?)
