That doesn't make Clojure any less functional. No matter which language you use, eventually it'll compile to machinecode and thats imperative by nature. Your code however, can be whatever it wants to be. In certain scenarios, the object boxing does come with a high pricetag in terms of performance, but there are always ways around it and usually only a few functions need tweaking. I will concede however, that those few functions typically end up losing their elegance.
