How would it be run without Emacs?

You might point out that there are things like elisp.lisp that purports to run Emacs Lisp in Common Lisp, but I'm not sure that's viable for anything but trivial programs. There's also something for Guile, but I remain unconvinced.

Maybe a Common Lisp core with an Emacs frontend running it in https://www.gnu.org/software/emacs/manual/html_mono/cl.html?

Why not just use the best known emacs lisp core, then? Like say emacs.

[agumonkey]

still in their main doc https://www.gnu.org/software/guile/manual/html_node/Emacs-Li...

[larsbrinkhoff]

Having read that, I'm even less convinced it's not more than a toy.

[convolvatron]

you could probably use the unexec tooling

[larsbrinkhoff]

I don't see how unexec would help with "decoupling the core from Emacs" since the core is written in Emacs Lisp.
