I'm part of the emacs community, and not part of the Guile community (though I am a fan of Scheme, just not Guile in particular, Chicken Scheme is more my speed) and I think a Guile-based emacs would be a huge step forward, and can't wait for it to Guile to be fully integrated and all the outstanding issues to be ironed out.

I really can't understand the objections from some people in Emacs land, except for those that would prefer a Common Lisp-based Emacs, but that's not what we've got. We've got Guile, and while that might not be as great as Common Lisp (in their eyes, not mine, for me Scheme is preferable), it's still a lot better than elisp. Rejecting Guile and sticking with elisp just makes no sense to me at all.

Keep in mind that having emacs be based on Guile does not mean that all the elisp emacs packages have to be jettisoned. They will still run as elisp under Guile, and you can continue writing scripts in elisp and have them continue to run under a Guile-based emacs.
