OK.  So item() would be available on Element after casting it to NodeList in 
those implementations.  I guess you're saying that the cast would not longer be 
unambiguous if there were multiple NodeLists that might make sense?  So 
childElements couldn't be implemented with a |return this;|?

That doesn't seem like such a terrible implementation burden to me, to be honest...
