lelitsch asks: "Does anyone have first hand experience with Groovy? I am just coming off implementing a Plone-based intranet CMS and got hooked on scripting languages and Python all over again. Since most of my projects in the near future are going to be in Java or have large Java components, I was wondering if it's time to trade Jython--which seems to be falling further behind the Python release cycle--for something else. Groovy sounds like a fun thing to look at, but it seems a bit new and thin. Also, what are other languages (JRuby and Rhino, for example) you have used to script in Java?"
