Hm, besides the project being dead, what is the advantage of an incomplete Lisp to C# compiler over Clojure on the CLR?
Or F#? Has no-one written something for Lisp-ish that talks F#?
Maybe someone would want to use Lisp to generate some C# code into an existing project? .NET is great for polyglot programming, but you can't really mix languages inside a single project.
