As you saw, my Scheme implementation (Scheme 48) isn't willing to do this---this is due to proper checking of read-only status for heap objects. Nothing to do with macros. Emacs Lisp could do it as well, in principle, although I'm sure there's code out there depending on precisely this "feature." -- Cheers =8-} Mike Friede, Völkerverständigung und überhaupt blabla
