Of course you're technically right, but should the manual mention in
the "quoting" section that using quote the way I did results in a
shared data structure? This part was surprising to me.
And I think it will be very surprising to others new to lisp.
Specifically, if you read the stackexchange thread Drew pointed to:
http://stackoverflow.com/questions/134887/when-to-use-quote-in-lisp
It seems I'm not the only one who didn't realize that quote does not cons.
