Ola Bini, a core JRuby developer and author of the book Practical JRuby on Rails Projects, has been developing a new language for the JVM called Ioke. This strongly typed, extremely dynamic, prototype based object oriented language aims to give developers the same kind of power they get with Lisp and Ruby, combined with a nice, small, regular syntax.
