Get up to speed with Clojure in this quick and practical primer. You'll learn the nuts and bolts of functional programming, data structures, sequences, destructuring, pattern matching, polymorphism, concurrency, conventions, and more. Author Mark McDonnell talks about organization with namespaces; how to change the language via macros; object-oriented programming; and creating command-line apps. Finally, he shows you how to write Clojure from shell languages and interfaces such as Vim.  

After reading and using Quick Clojure, you'll come away with first-hand knowledge and advice on how to quickly adopt, use, and apply Clojure without all the theoretical baggage that bigger books can sometimes bring.

Programmers with experience.  A Java background would be helpful, but not required.
