List Encodings
An encoding of (immutable) lists of varying length must define a constructor for creating an empty list (nil), an operation testing whether or not a list is empty (isnil), an operation to prepend a given value to a (possibly empty) list (cons), and two operations to determine the first element and the list of the remaining elements of a nonempty list (head and tail).
