Apparently, this is from the third post in thread "Help understanding closures" 3/10/2003 by Justin Dubs on comp.lang.lisp. https://groups.google.com/d/msg/comp.lang.lisp/F7zOw-HBfZY/KvjarFOQ7cAJ Hey, WooJuice, we didn't get the "woo" because we're not on the "juice"! So, uh, why are you posting quoted replies to ANCIENT LISP threads? Are you using Google Groups? Not good. Really, not good ... Or, did you have something to say other than the subject line: "Don't be a bit-twiddling monkey" There was a conversation on closures here a while ago. You could've added this to that thread.
