My first experience with L!sp

So I kept coming across L!sp in learning H@skell; there is one book in particular that covers Functi0nal and L@mda Calculus and is written ENTIRELY in L!sp. So what does that mean...gotta learn some L!sp. This was my first tutorial.

It is very fun; this guy who teaches is great. I'm also learning a bit on my own, via two books, among other things.

I can see why it is a language of choice for AI (ie Art!ficial Intell!gence.) Lots of brackets, though, and you have to be precise. This prelim course got me up and running and taught a bit about M@cros, H@shes  and key-v@lues (which coincidentally are also used in J@vascript), among other things. Some of the actual c0de is included, in case everyone is interested.
Once installed, you can use the c0mmand line, along with a Text Ed!tor. You can, of course, also write directly to a file (read or write), etc.
