[$] Emacs in Scheme

During EmacsConf 2024, which
was held online in early December 2024, Ramin Honary gave a talk about Project
Gypsum, which is his effort to rewrite Emacs in Scheme. Unlike most other Emacs clones,
which simply replicate the key bindings, Gypsum is also implementing Emacs
Lisp (or Elisp). Honary is initially targeting Guile, which is an
implementation of Scheme, but wants to make the code portable
to any implementation of R7RS Scheme.
