subsumes

Relational term subsumption for SWI-Prolog

subsumes/2 is intended as a relational drop-in replacement for the anyway deprecated terms:subsumes/2. It can handle cyclic data, as well as cases where cyclic data would be induced.

?- f(X, Y) subsumes G.
G = f(_A, _B),
X subsumes _A,
Y subsumes _B.

?- f(X) subsumes Y, Y subsumes X. % Example with induced cyclic data.
X = Y, Y = f(Y).

?- X subsumes Y, X = g(_).
X = g(_A),
Y = g(_B),
_A subsumes _B.

See the unit tests in [test/subsumes.plt](test/subsumes.plt) for more examples.
