Yes, Java7 and invokedynamic coupled with type inference in ABCL's
compiler should lead to a great improvement from my understanding at

But the changes needed would be quite substantive so I wouldn't count on
it unless there's money behind it.

Notice that ABCL is very young, and, from what I know, Clojure has one
person (the original author even!) work on it full-time.
