What about the implementation of CL (loop ...) construct?

      (loop for i from 1 to (compute-top-value)       ; first clause
            while (not (unacceptable i))              ; second clause
            collect (square i)                        ; third clause
            do (format t "Working on ~D now" i)       ; fourth clause
            when (evenp i)                            ; fifth clause
              do (format t "~D is a non-odd number" i)
            finally (format t "About to exit!"))      ; sixth clause
