 I get an error whenever I call a function that uses the simple method
 combination shown here.

 {{{
 CL-USER> (define-method-combination progn-with-whole ()
            ((methods ()))
            (:arguments &whole whole)
            `(progn (format nil "using ~a" ,whole)
                    ,@(mapcar (lambda (method) `(call-method ,method))
                              methods)))
 PROGN-WITH-WHOLE
 CL-USER> (defgeneric test-&whole (x)
            (:method-combination progn-with-whole)
            (:method (x) x))
 #<STANDARD-GENERIC-FUNCTION TEST-&WHOLE {34315D04}>
 CL-USER> (test-&whole 4)
 }}}

 Here is the error:
