Another great resource for Clojure is ClojureDocs. The doc for 'future' has a simple example: http://clojuredocs.org/clojure_core/clojure.core/future
Not only does it show you the doc string and an example, if your scroll down you can see the source code for the function. You'll see that lot of language level constructs (future, promise, etc) use some form of the java.util.concurrent stuff, but add on to it. Some stuff (agents, atoms, etc) can be found here: https://github.com/clojure/clojure/tree/master/src/jvm/clojure/lang if you want to look through the entire source (I definitely recommend it!)
