This is really cool. I'm interested in checking out Common Lisp coming from Clojure, but I really like Clojure's syntax. A macro-heavy library that could recreate the syntax would be awesome, although I'm sure I couldn't collaborate with anyone at that point.
Emacs Lisp has now support for lexical scope.
