That's nonsense. Emacs Lisp has served well as programming language for 30 years. There is some really fantastic code written in Emacs Lisp. Dynamic Binding is a minor issue. People have been writing whole operating systems in dynamically bound Lisp and I'm not talking about GNU Emacs itself. There is no GNU Emacs based on Guile in the sense that the Elisp code has been translated to Scheme. All there is is an Emacs based on the GNU Guile runtime. The code is still written in Emacs Lisp - it just runs on a different runtime. From https://www.emacswiki.org/emacs/GuileEmacs https://www.emacswiki.org/emacs/GuileEmacs > Guile-based Emacs is a branch of GNU Emacs that replaces Emacs’s own EmacsLisp engine with the Elisp compiler of Guile. It's a different compiler. You can write stuff in Scheme, too. But who would do it, since then it would not be compatible with the main GNU Emacs editor...
