subsumes(+Generic, @Specific)

True if Generic is unified to Specific without changing Specific.

deprecated: It turns out that calls to this predicate almost always should have used subsumes_term/2. Also the name is misleading. In case this is really needed, one is adviced to follow subsumes_term/2 with an explicit unification.
