Yes, it's very unfortunate that Manning released Clojure in Action without a final pass to make it Clojure 1.3 compatible. I talked to them about it when they still had time to make changes but they decided to go ahead and publish a book that is tightly wedded to Clojure 1.2 after Clojure 1.3 had been released. I think it was a disservice to both the author and the community :(
