Well, that's not quite true.  In a null lexical environment this will
work just fine, and I very much doubt that a Lisp beginner is going
to be throwing macrolets around.  You're right that your way is better
programming style (which is why my note was heavy with disclaimers)
but from a pedagogical point of view I thought it would be better not
to try to explain closures to a Lisp beginner in a short note.
