Today John Lam announced the first release of IronRuby source code. Of interest to me in the announcement was the following quote:
"We're also happy to announce that we will be accepting source code contributions into the IronRuby libraries."
This policy is what many users of IronPython have been wanting since it's first release. Since both language implementations are released under the same license, hopefully Microsoft will see fit to change their policy for IronPython as well. And once the DLR reaches 1.0, hopefully we will be able to contribute to the IronPython compiler codebase as well.
So congratulatons to the IronRuby team on the progress to date, great to see dynamic languages getting more exposure in the .NET world.
