The first drop of IronRuby source code, the baby of John Lam, has been released to public. It requires .NET Framework 2.0 right now, and it’s built on top of the Dynamic Language Runtime (DLR). It should be in Rubyforge by the end of August.
This is an exciting pre-release since IronPython was announced, proving to the masses that the dynamic languages can be built on top of the CLR. Well, go grab it and try it out.
