Have you ever heard of IronScheme?
IronScheme [aims] to be a R6RS compliant Scheme implementation based on the Microsoft DLR.
These aren’t just nebulous goals either, they’ve actually got the interpreter up and running!
With so much development going on around the DLR right now; I’m going to pay extra special attention to when the *next* Lang.NET symposium is going to happen. It looks like a lot of fun!
