 Alright, let's try to implement Iter. This time we won't be able to rely on
 List giving us all the features we want. We'll need to roll our own. The
-basic logic we want is to hold a pointer to the current node we want to yield
-next. Because that node may not exist (the list is empty or we're otherwise
-done iterating), we want that reference to be an Option. When we yield an
-element, we want to proceed to the current node's `next` node.
