Clojure is lisp , so exploring other lisps will help many get used to parts of the lisp culture or the general way of doing things. Remember that Clojure is greatly reduced with Common Lisp.
Clojure lazy , so learning Haskell really helps you get used to the idea of โโreal lazy programming.
Clojure is parallel , so learning a bit of Erlang will help, although you will need to remember that Erlang contains a lot of information about distributed programming, and Clojure - about parallel programming, which is not necessarily distributed.
