XML, good point. XMLisp combines S-expressions and XML into X-expression via
CLOS, MOP, Lisp reader and Lisp printer:
- paper: http://www.cs.colorado.edu/~ralex/papers/PDF/X-expressions.pdf
- code (all in one file)
http://code.google.com/p/xmlisp/source/browse/trunk/XMLisp/sources/XMLisp/XMLisp.l
Another cut example I did many years ago (showing my NYU colors) along the
lines of what Pascal shows here is the "SETL syntax" in CL. I still have the
code. Here is the stupid PRIMES
(defun primes (max)
[n in (range 3 max 2)
such-that (not (exist m in (range 3 (min (1- n) (+ 2 (sqrt n)))
Well, since we are talking about XML stuff, I have another shameless plug
myself then :)

All in all the pretty-printer is very nice, it'd be nice to have an agreed upon
jazzed up version of CLOS dispatching.
