 ==== [blue]*`$$()`* -- Expansion special function for iterators
-The [blue]`$$()` operator is a special function already seen applied to contexts. It can also be applied that can be used with iterators. When applied to an iterator, it returns a _linked list_ of all the remaining elements of the collection. The state of the iterator is updated to the end of the collection. If there are no more elements to iterate over, it returns an empty list.
