Jarc - An Arc interpreter written in Java

Interesting. I have only tried Rainbow, which is another Arc implementation for the JVM http://github.com/conanite/rainbow/blob/master/README

Looks fun. One of the few remaining complaints I have about Clojure is the lack of a Lisp-style debugger, and Jarc has one. No compiler, though.

I'm looking forward to the Dot-Narc implementation for Windows users.
