As I understood it, the goal is not to simply allow Guile alongside Elisp, with the intent to confuse users, but to eventually replace Elisp completely. Guile devs are claiming that their Elisp implementation running on top of guile provides several substantial benefits over Emacs own C-implementation of elisp: * higher speed * native threads * lexical scope * ffi * module system * goops, guiles object system Emacs is a key GNU project, but to the detriment of the overall project philosophy, it uses an extension language no other GNU project uses and never will use. Elisp may be working for emacs, but it is isolating it from all other apps, since nobody else uses Elisp. The long term goal of GNU is to "emacsify" the whole system, i.e. to enable emacs and other apps to talk to each other over guile es their universal scripting interface.

Do you have any idea how much stuff we've written in Elisp? It's. Not. Worth. It. You people don't even listen when we try to explain that lexical scope is unnecessary and potentially even a bad idea. Threads? Come on. :\

  > You people don't even I'm not "you people", I'm not affiliated with Guile in any way. However, you are wrecking your brains over something without being fully informed. It is not and never has been intended to _rewrite_ anywthing written in Elisp. Thats why Elisp itself has been to a large part already rewritten in Guile, and it is planned to gut emacs and replace the current C-Elisp engine with the new Guile-Elisp engine. Whether this will or will not work out as intended is a completely different story. But the fact remains that Elisp, in the grand scheme of things, is an isolated island, and as such does not fit into the overall design goals of GNU stated over 20 yrs ago, so there are people working on this. Even Google sponsored two GSoC projects for two years to rewrite Elisp in Scheme.

  Could you expand on "lexical scope is unnecessary and potentially even a bad idea"? I'm really curious given that fact that almost all the languages I use support lexical and not dynamic scope.
