I removed a bunch of cl-stuff that was fine with just stuff - I hope. Also replaced `apply' with `funcall' to not have the trailing nil argument - ugly - IIRC those were both harmless, right, it was `eval' one should avoid? Now the code looks pretty clean! But looks can be deceiving ... The next step is just to add a bunch of specific interfaces to call it. ;;; -*- lexical-binding: t -*- ;; ;; this file: ;; https://dataswamp.org/~incal/emacs-init/buffer-crunch.el [version 0.3.2] ;; ;; All features shown as examples: ;; ;; 1.
