Emacs is an open&#x2F;unsafe architecture. Whatever I write in Lisp in my .emacs file becomes part of my implementation. It&#x27;s on the exact same level as the Lisp code rms writes which is bundled with the releases.<p>Vim scripts like Chromium and Firefox plugins are inferior to their host processes. They can only modify the application behavior through a set of (supposedly) safe api calls. Since Elisp packages aren&#x27;t second class citizens, like Vim scripts, it changes everything.
