Guile-powered Emacs: A Bold Rewrite Project

Emacs, renowned for its extensibility, faces performance and expressiveness limitations with its core language, Emacs Lisp (Elisp). To address this, the Guile-Emacs project aims to replace Elisp in Emacs with Guile Lisp. After years of development and dormancy, Guile-Emacs has been revived by developers Robin Templeton and Larry Valkama. The project aims to leverage Guile's compiler and performance advantages to improve Emacs' speed and extensibility while maintaining Elisp compatibility. The ultimate goal is to rewrite a significant portion of Emacs's C code in Lisp, significantly enhancing its customizability. While facing technical and political challenges, the project presents exciting possibilities for the future of Emacs.
