  32 @deffn {Scheme Procedure} nil-cons x y
  33 @deffnx {C Function} scm_nil_cons (x, y)
  34 Create a new cons cell with @var{x} as the car and @var{y} as
  35 the cdr, but convert @var{y} to Scheme's end-of-list if it is
  36 a Lisp nil.

  39 @deffn {Scheme Procedure} nil-eq x y
  40 Compare @var{x} and @var{y} and return Lisp's t if they are
  41 @code{eq?}, return Lisp's nil otherwise.

  44 @deffn {Scheme Procedure} null x
  45 @deffnx {C Function} scm_null (x)
  46 Return Lisp's @code{t} if @var{x} is nil in the LISP sense,
  47 return Lisp's nil otherwise.
