zip method
Pairs corresponding elements together.
['one', 'two', 'three', 1, 2, 3].zip() returns
['one', 1, 'two', 2, 'three', 3].
Sub-iterables must have same type of elements, or be the same type of iterable (List, Set, etc.).
Implementation
Queue<Queue<E>> zip() {
return h.zipIterable(this).toNestedQueue();
}
