I just picked up the MEAP (Manning Early Access something-or-the-other) edition yesterday, and read the first 2 chapters.<p>Naturally, the book is an early access so it looks like it use a second pass with an editor. That aside, I really like the way the authors spend some time discussing the features of the language, and why they are implemented the way they are in Clojure. They do a great job of explaining Rich's design decisions, how they affect the way you would normally approach a problem in Clojure, the pitfalls, along with comparing some of them (esp. the concurrency aspects) with other languages like Erlang.<p>I was a little skeptical before buying this book, but I am glad I did. fogus and the others have done a pretty good job so far. Definitely worth the money.
