Clojure Solutions
Solution 1 - Clojure
Even shorter :
user> (clojure-version)
"1.2.0-beta1"
user>
Oops, I have to upgrade...
Solution 2 - Clojure
Very close.
user> (println *clojure-version*)
{:major 1, :minor 2, :incremental 0, :qualifier }
nil
Most builtin "global" variables like this have Common Lisp-style asterisk "earmuffs".
Solution 3 - Clojure
Just typing *clojure-version* will do the trick.
*clojure-version*
=> {:major 1, :minor 3, :incremental 0, :qualifier nil}
Solution 4 - Clojure
Extra repl examples
