YAP implements a style-checker thay currently verifies whether:
1 named variables occur once in a clause.
2 clauses from dofferent predicates are mixed together.
3 clauses for the same predicate occur in different files.
One can declare a predicate to be discontiguous (see the
discontiguous/1 declaration) and/or multifile/1.
