The Emacs C codebase is, to most effects, written on a dialect of C that requires learning by its own. In principle, it is possible to create a language which is similar enough to Lisp that the amount of learning it requires is similar in magnitude to the Emacs C dialect for someone who already knows Lisp, but being as optimizable as C and much more expressive and maintainable. (Some people would retort that this was already tried: that Emacs variant written on Common Lisp) I know this is just wild dreaming given the current status of Emacs. [snip]
