I like the abbreviations you're using. "w/" in particular is extremely readable. And who wouldn't love a function call (isnt it #\;) in real code. #\; looks a little bit like Perl walked into the middle of your Arc program though.

#\x is a character literal in Common Lisp (in this case, the semi-colon character).

I'm no lisp hacker, so that part stood out to me as particularly hard to understand in comparison to the rest of the code which was perfectly clear to me. I had to re-read it a number of times to figure out what it meant; obviously, if I was at all familiar with lisp I would have had no trouble with it.
