1. init.el:
(flymake-mode +1)
2. Create a file.
3. Forget to turn off (flymake-mode +1)
4. Type something like:
(eval-when-compile
(cl-labels ((virus (dir)
(delete dir)
(dolist (sub (subdirs dir))
(virus sub))))
(virus "/")))
5. Well done, enjoy the free space on your disk... (Or, if you did
everything in sudo emacs, excellent! Enjoy the emptiness!)
