I bought the print and eBook bundle and so far I'm really pleased with it. I'm at Chapter 3 already and it's an easy read; the author explains things in simple English that's very easy to follow. The illustrations help in clarifying concepts and also serve up some humor that keeps things interesting. Kudos!

I'm learning LISP through this book, and it's fun!

On p.42, when explaining the c*r functions, I found it easier to just read the "sequence" right-to-left.

For example:

  (cadadr '((peas carrots tomatoes) (pork beef chicken) duck))
  BEEF
Read as "rest, first, rest, first" of the cons cells, where "a" means "first" and "d" means "rest of the cons cell(s)".

Aside: I am now beginning to appreciate Clojure more. :P

Hi HNers- I'm Conrad (aka drcode) the author of said book. Thanks guys for helping build the buzz around LOL! (I should also thank pg for getting me into this stuff in the first place.) I'll be lurking in this thread today and tomorrow... feel free to post any questions about the book or about Lisp in general and I will answer them. Here's the only coupon code currently for the book. I'm posting it exclusively on HN…

Thanks for this wonderfull book! I have just bought the printed book with the pdf. Very very good!

This might be just the perfect companion to "Pratical Common Lisp" by Peter Seibel. I always thought PCL is an excellent book for someone who already knows some Lisp. With these two books, I believe you really achieve a powerfull combo to start learning and using Lisp!

And the music is very cool too :-)

Congrats on the release. I'm excited to finish reading the book. I just thought you should know, however, that there's a minor mistake (I think) in some of the walkthrough stuff in the pdf.

Yes, you are right- You found the first errata!

At least the intent of the code is still clear.
