IronScheme
I have been watching the development of IronLisp, a Lisp compiler for the DLR for a while now. A little while ago it was released onto codeplex and more recently the project was dropped and reformed as IronScheme (Scheme being a Lisp variant). Great to see another language on the DLE, apart from IronRuby and IronPythoin (and LOLCODE :D) I wonder what other languages are targeting it and if MS have a research\compiler program for it yet?
