Now, I am VERY much in support for getting various languages running on the JVM. I think that is the future for Java as a platform. I would LOVE to see JRuby kick ahead, see Groovy come to 1.0, and any other cool DSL that would allow us to express ourselves in a different way on the Java platform.
However, what is with standardizing these languages? In my opinion it made NO sense for Groovy, and I thought we had seen this.
Best of luck to the BeanShell guys, but wow.
