This seems a little overkill to me; is there a reason not to just inject an invisible node (a whitespace node, comment node, or even an empty `` in the worst case) immediately after every Iterator's `sourceNode`, and retain that as the `siblingNode`? It seems less fragile to me, but I may be missing something obvious...
