Another new language for the JVM

Some say that it is java, others say that it is Ruby, but in fact it is a brand new experimental language: Mirah.

Mirah (nee Duby) is a new experimental language born out of the JRuby project. In order to make implementing Ruby on the JVM easier and more approachable for Java and Ruby developers alike.

Here you can find the project page. And for those that want to understand why another language, here you can find an interview with one of the Mirah's creator Charles Nutter.
