This issue was originally filed by @seaneagan

Currently, Collection subinterfaces (List,
Set, HashSet, Queue) inherit Collections.filter which returns a generic Collection. This means that when
you filter, part of the interface contract is lost. It would be
better if each subinterface specialized filter to return the
subinterface itself. For example, List would specify:

List<E> filter(bool f(E element))

This would pertain to Collection.map (issue #945) as well, except maybe not for Set.map, since the mapped to values would not necessarily be unique.
