Offer scheme as an alternative to elisp for some other reason (if so, > which?). guile-emacs replaces Emacs's own Emacs Lisp engine with Guile's (without breaking backward compatibility). So: * Emacs Lisp will execute faster (Guile VM bytecode is more efficient) * It will be easier for Emacs Lisp to implement some new language features * Emacs Lisp will be able to interoperate with languages on the Guile VM (not only Scheme) So I think all 3 points are purposes (or side-effects) of guile-emacs, although the first one should be "write *a part of* the underlying core in Scheme". I think one of the "some other reason" should be "satisfying people who like Scheme (or other languages run on the Guile VM) because it's cleaner and simpler than Emacs Lisp".
