Tips for golfing in Common Lisp What general tips do you have for golfing in Common Lisp? I'm looking for ideas which can be applied to code-golf problems and which are also at least somewhat specific to Common Lisp (e.g. "remove comments" is not an answer).

Please post one tip per answer.
Use ' (quote) as synonym for "" for single words.

Quote stops evaluation of symbol, allowing you to e.g. print it. Note that the casing is dependant on *print-case* variable (most of the time it's in the upcase).

(print"yes")
(print'yes) ; saved a byte!
