You'll find lispm's, from a sibling comment, even clearer:

  (defmacro debug-it (&body expressions)
    `(progn
        ,@(mapcar (lambda (expression)
                    `(format t "~%~a: ~a" ',expression ,expression))
                  expressions)))

That's Common Lisp. I probably could have made mine similarly clean, but I was too lazy to do so :-).

Anyways, hats off to lispm, because he's the one who actually did it.
