The reference documentation for the difference()- and intersect()-steps described their result as a list, but both steps return a Set: element order is not preserved and duplicate elements are removed. Both sections now state this while keeping the existing description of the A-B and intersection semantics, the array/Iterable input expectation, and the IllegalArgumentException thrown for other input types (including null).
