You can probably boost n-body on 1.2 by replacing arrays with deftypes. (definterface BodyIsh (^double getMass []) (setMass [^double x]) (^double getPosX []) .....)
(deftype Body [^double ^{:unsynchronized-mutable true} mass ^double ^{:unsynchronized-mutable true} posX .....] BodyIsh (getMass [x] mass) (setMass [x m] (set! mass m) .....) And then rewriting the program using Body (and a type annotation on bodies, of course) I used interfaces and not protocols here because I am not sure 1.2 supports protocols with primitives.
