Yes. I think that's likely why the goal for guilemacs has always been to be able to support elisp and make the transition as smooth as possible, without removing elisp support.

One interesting thing about Guile's VM (at least last time I checked) is that was designed to support multiple languages, not just Guile Scheme.

Hmm.. I wonder if that's also why there was not a lot of push before, since this would open the doors to js in emacs too, which is a thing RMS did not want.
