Notable change: fix for CLJS-418, the broken dependency
It's probably possible but too broad a scope for GSoC 2013. I think the
community would be better served by directly contributing to core.logic
core.typed both of which could use lots of help :)

That looks like some highly optimized JS to me ;)
I think I'll stick with writing my fast code in Clojure thank you very much.

Fair enough. My point was simply that Clojure implementations have a small
learnable subset that performs well when performance is desired -
primitives, loops, arrays, deftypes, etc regardless of host. It's
Er re: assigning stack based locals. Forget wasting time making a tuple
type, probably best to just do that with a small mutable array. This worked
ok for us when porting some Java persistent data structure code to

to approach it. Curious to know how it goes though!
