Really good work. I spent 15 minutes reading through this book over my first cup of coffee this morning.
I stopped using Clojure about 5 years ago, after two long consulting jobs using Clojure. I decided Clojure was not a perfect fit for me (and, really, neither is Common Lisp, Racket, and Haskell - more favorite languages) but I am very happy to see the Clojure ecosystem still creating such great tools around the language and functional composition.
