Roles shouldnt be put up as rust, but there is clearly rust in the github repository. Its not a lot but my understanding is the usage is somewhat growing.
I'm very interested in guile-emacs, not because I think it'll replace main emacs, but I do think it'd be really neat to have my config in a 'cleaner' lisp like scheme, a clojure like language, lokke[0], or even python[1]
