Beautiful! This page covers everything we were confused about
yesterday. And you are right - I read Love's 3rd edition as more 
ambiguous than wrong, but he does say the "head" node is not a member
of the list, and that's more wrong than ambiguous. Morevover, the
biggest problem with my first implementation was that I believed him.
