If $num is greater than the number of items remaining in the queue, only the number remaining will be dequeued.
Returns an array of items if wantarray, otherwise returns the last of the dequeued items, which allows singleton dequeues:
my @results = $queue->dequeue($num);
my $single = $queue->dequeue;enqueue(@items)
Add @items to the queue.
ready
Returns the number of elements in the queue.
requeue(@items)
Inserts @items to the top of the queue in an order such that dequeue(1) would subsequently return $items[0] and so forth.
