> Crazy side of me would like to see it fully written in a safe(r) language like rust, swift or zig. Emacs Lisp is a very safe language. Even though the Emacs core is written in C, that is immaterial and impalpable to Emacs users as they only interact with Emacs Lisp. What benefits would Rust / Swift / Zig bring to an average Emacs user? > Basically your config would be a recompiled subsystem, loaded at runtime, or you'd recompile the whole editor. elisp -> bytecode compilation in Emacs… predates humanity? https://www.gnu.org/software/emacs/manual/html_node/elisp/Byte-Compilation.html https://www.gnu.org/software/emacs/manual/html_node/elisp/By... The entire stash of Emacs packages compiles into the byte code at the package installation time, anyway. Personally, I even byte-compile-file my ~/.emacs to eke out an imperceptible speed improvement at the startup time, which is slightless less than entirely useless but it warms my heart that I can do it. Recent versions of Emacs can also compile Elisp into the native code: https://www.gnu.org/software/emacs/manual/html_node/elisp/Native-Compilation.html https://www.gnu.org/software/emacs/manual/html_node/elisp/Na... > Better key handling and none c-x nonsense. Perhaps you do not need Emacs then.
