It occured to me over lunch that this list type is actually missing exactly those routines (CDR and its tail-oriented equivalent) if we were to truly make it usable in the Lisp style. So perhaps Front and Back should stay as is, First and Last should also become Front and Back, and Head and Tail should be new functions returning the *rest* of the list minus Back and Front respectively? --- T.E.D. homepage - http://www.telepath.com/dennison/Ted/TED.html No trees were killed in the sending of this message.
