Compiling to LLVM is an interesting prospect, because if you could make the language dovetail nicely with, meaning compile functions into LLVM functions and use their datatypes fully you could presumably be highly interoperable with other languages(?). Sounds like it could be a serious departure from the Clojure standard though, but perhaps another Clojure inspired LISP. Still, LLVM won't give you a run-time, which seems to be the main problem.
