Re: NIL cons cell

Notice on the representation of NIL. Is this always an empty cons cell?

  NIL is a special value that is /not/ the same as `(NIL . NIL),
  which is a dotted pair ("cell") with its CAR and CDR being NIL.

  The notation `() for NIL does /not/ mean that NIL is represented
  by an empty cons cell.

  `(1 2) is `( 1 . ( 2 . NIL )).
