If we (emacs users) can have an emacs that has a "modern" backend & language but is bug-compatible with the extant elisp code, I think that would be grand. Particularly nice would be thread support. I'm pragmatically indifferent as to whether the backend is scheme or common lisp (I'd personally prefer Common Lisp, but whatevs).
