There have been Common Lisp and Scheme implementations in the JVM for ages (Kawa, ABCL, and many others -- I wrote one myself called Skij). It's not clear to me why Clojure took off when those others didn't. But if reinventing Lisp is what it takes for Lisp to get traction, I'm for it despite my CL roots.
