Clojure is great!

I've been playing with Clojure for a couple of months now and I want to share with you some thoughts why I think it is a great language.

Clojure is a Lisp

Many wise people have written great things on Lisp, so I'm not even trying to present arguments for it; just try out these:
  • http://www.paulgraham.com
  • http://www.gigamonkeys.com/book
Clojure integrates easily with Java libs

Everybody knows it. Nothing interesting to add here.

Clojure implements modern concurrency techniques

Clojure implements STM(http://en.wikipedia.org/wiki/Software_transactional_memory). It features Atoms (abstractions for managing state synchronously), Agents (abstractions for managing state asynchronously, by applying function to agent's state), and lock-free handling of scenarios that would have to be handled with mutexes in other programming languages.

Don't be deceived that Clojure is "nice, because it revitalised Lisp or JVM". The key point is that it features modern approach to concurrency. Read this excellent explanation by Rich Hickey:
