I think the proposed solution there is:
  - example in Javadoc, and/or static helper

static <U> FlatMapper<T,U>
flatMapperToCollection(Mapper<T,Collection<U>> m) {
     (t, sink) -> m.apply(t).forEach(sink);
}

So users can say

   stream.flatMap(flatMapperToCollection(t -> getColl(t)))

and the javadoc can point them to that.
