It is better design. You've separated your concerns when you keep your collection separate from the thing the collection contains. This is a bit like a box that contains other boxes that also contains itself. The primary thing here is to keep the collection object separate from your contained object. Or also, to keep the container out of the things that it contains. You might, if you wished, provide a method on your collection which could do the ->next operation for you.
