[$] Emacs in Scheme

During EmacsConf2024, whichwas held online in early December2024, Ramin Honary gave a talk about ProjectGypsum, which is his effort to rewrite Emacs in Scheme. Unlike most other Emacs clones,which simply replicate the key bindings, Gypsum is also implementing EmacsLisp (or Elisp). Honary is initially targeting Guile, which is animplementation of Scheme, but wants to make the code portableto any implementation of R7RS Scheme.
