Clojure for the Erlang VM
Erlang is a great language for building safe, reliable and scalable systems. It provides immutable, persistent data structures out of the box and its concurrency semantics are unequalled by any other language.
Clojure is a Lisp and as such comes with all the goodies Lisps provide. Apart from these Clojure also introduces powerful abstractions such as protocols, multi-methods and seqs, to name a few.
Clojure was originally built to simplify the development of concurrent programs in the JVM. Some of its concurrency abstractions could be adapted to Erlang, but this is not the main goal of this project. Its main goal is to combine the power of the Erlang VM with the expressiveness of Clojure to provide an interesting, useful result that might make the lives of many programmers simpler and make the world a happier place.
