<p class="purpose">Action name lists provide a disjunction in the choice of action made by an action pattern. For instance, "taking or dropping the disc" results in a two-entry ANL. An empty ANL is also legal, and means "doing something" -- the generic I7 text for "any action at all".</p>

takes a pair of objects A, B and returns 1 if A makes a more specific
