I'm with Jonathan on this. I don't really see much of a benefit. popFront, empty, front are very easy to define and simple to use.

Java uses getNext for its iterators. Though it calls it 'next' and throws an exception when trying to call without any elements. This leads it to also provide a hasNext function.
