One question here: how tight the compiler is binded to OCaml semantics? Besides Reason, do you think it's possible to build a frontend for other languages and integrate the backend of BuckleScript to generate beautiful JS as well? Or in other words, what property do you think a language should have so we can generate this level of beautiful JS outputs?

BTW: Please understand I'm not objecting OCaml, I do believe OCaml is an awesome language, but my point is: if possible, we should make this beautiful backend for generating human-readable JS more accessible than restricting it to OCaml only, shouldn't we :)
