Not exactly, it uses square brackets for vectors sometimes and curly brackets for maps sometimes, yet other times it uses square brackets for maps: (let [a 1 b 2] (+ a b)) Instead of: (let {a 1 b 2} (+ a b)) (I think my map notation may be wrong, I always just bounce off Clojure so I'm bound to make mistakes).
