Summary0000112: set_* modules inconsistent
Descriptionset_bbbtree, set_ordlist, and set_unordlist all have a predicate member(T, set(T)) with modes semidet and nondet, and a predicate contains(set(T), T) with mode semidet.

set_tree234 reverses the order of the arguments of member relative to these three modules, and set_ctree234 drops member and provides instead one_member(set(T), T) with only mode nondet.

At the very least the order of arguments to set_tree234.member should be reversed, or the predicate renamed.
TagsNo tags attached.

Whoops, meant to say same applies to insert, delete, etc.

The inconsistency in the argument orderings is deliberate in the sense that the set_tree234
orderings are what we want (because they are more uesful with higher-order programming),
the versions in the other set modules will eventually be changed to conform to this; but not
until after the next stable release.

OK, good to know, thanks.

The argument orderings will be modified sometime after the 0.14 release.
