I've been using emacs for a few months now (it's surprisingly good), and am starting to run into wanting to do little modifications. Speaking as a non-lisper, I really wish a rewrite existed in a more modern language. I don't wanna start an argument about lisp here but there is a reason people don't use it for major developments, and it's not the performance. But it would be unfair not to point out that you can extend emacs in a variety of languages including python. Its just a bit messier.

First of all, various members of the Lisp family are used for major developments.

Secondly, rewriting Emacs would be a major undertaking and which modern language would it be? My choice would be Common Lisp, for other developers it would be Clojure, Haskell, Python, Ruby, etc. Whatever choice it would be, you'd lose developers who would rather see Emacs rewritten in one of the other languages. Even worse they might spawn forks in their own favourite languages.
