Woo hoo! This is great news for getting Ruby into the mainstream. It looks like we might get Ruby as a first class citizen in the Netbeans IDE too, which has had pretty non-existant non-java language support to date. And MicroSoft are sponsoring the development of Ruby on the CLR, so lets hope that can brought up to be on a par with Iron Python. In the main Ruby development tree we have greater speed on the way with the YARV VM for Ruby 2.0.. What can possibly stop the rise and rise of Ruby now?
