Well, a tree often has information at the node, while a list does not. 
You can map either to the other(as well as most any data structure, 
AFAICS) so the question of which is more appropriate would seem to be a 
matter of which maps more directly to structure of code. For this a 
tree with 3 pieces of info(symbol, attached, next) on each node seems 
to be enough to uniformly represent the semantics of a pure OO language 
(one where the only operation is a message send).
