Hi Fredrik,
Similar results can be accomplished using vectors and
destructuring in Clojure.
user=> (defn foo [] [:one :two :three])
#=(var user/foo)
user=> (let [[a b c] (foo)] (println b))
:two
nil
user=>
The destructuring capabilities of "let" are quite nice.
A bunch of examples are available in the let reference:
