A Smalltalker (another *great* language) who enjoys LISP almost as much took note of a thread about Aha! moments in LISP.

So what were *your* Aha! moments? To me - to date - these were some of mine: * Realizing that text formatting had *nothing* to do with printf() formatting. * Building an application - like layers on an onion (or better yet, a baseball): start with a core, wrap it, wrap that with another function, wrap that.... * Understanding how macros really worked (from "On Lisp") What are yours?
