You have generators in elisp already. Wanting to use one language is,
IMHO, a poor choice for wanting to completely swap out a language. I am
opposed to Guilemacs, not only on technical grounds, but also because
elisp is essential to Emacs (and not just an optional extension system),
and I want its implementation to live alongside the rest of the Emacs
core code.
