Kawa guy. Kawa was written by a single person, Per Bother, in his spare time. Clojure has a massively larger mindshare and collection of coders behind it. Ask yourself: why has Clojure been so slow for so long?

Actually in my experience this is where Clojure is very slow indeed. If Clojure has to convert everything to Refs, it gets extremely slow (in our tests on my simulation system, up to 1000x slower than Kawa. I am not making up that number.).
The did it for a dacade and rich does it for a couple months and you bash him? We arn't the kawa guys faster after a decade.
Clojure is faster in other stoff like interop witch is really importend on the JVM. Can Kawa write down-to-java speed types?
