evaluator
     
         Geoff Burn defines evaluators E0, E1, E2 and E3 which
        when applied to an expression, reduce it to varying degrees.
        E0 does no evaluation, E1 it evaluates to {weak head normal
        form} (WHNF), E2 evaluates the structure of a list, i.e. it
        evaluates it either to NIL or evaluates it to a CONS and then
        applies E2 to the second argument of the CONS.  E3 evaluates
        the structure of a list and evaluates each element of the list
        to {WHNF}.  This concept can be extended to data structures
        other than lists and forms the basis of the {evaluation
        transformer} style of {strictness analysis}.
