Sun has just now decided that adding support for dynamic language to the JVM might be useful. It's only been about nine years since I and many others have been making awkward implementations of Lisp and other dynamic languages on the JVM. I did my work in this area when I was at IBM research working on Java tools, and I was working with a project that was working on a JVM implementation, and I tried to get them interested in adding some extensions like this. No go back then, but better late than never.
