I was thinking in terms of how you would literally write the source code 
in imperative and functional languages.

   var total = 0;
   var position = list.start();
   while (position != null)
   {
     total = total + position.get_value();
     position = position.get_next();
   }

Pretty much a verbatim match there.

And of course, accessing parts of a list requires splitting them, and 
recusion isn't looping. ;-)
