Thanks guys. I had a feeling that it wasn't doing the calculation twice the
way it was coded in the book.

It's definitely got to do with the code, the right way to test it out
will be to wrap the form in a function and then calling it twice. Like
so -
(time
(let [x (fn [] (Thread/sleep 2000)
(+ 1 1))]
[(x) (x)]))
;=> "Elapsed time: 4002.0 msecs"
;=> [2 2]
Hope that helps
There is an example in the book The Joy of Clojure on p.262 that uses
futures that I evaluated in the REPL.
user> (time
(let [x (future (do (Thread/sleep 2000)
(+ 1 1)))]
[@x @x]))
"Elapsed time: 2000.809 msecs"
[2 2]
I figured that taking out the future would cause the execution to t
