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".
