Nowadays, *all* files with a `.el` extension should have `-*- lexical-binding:t -*-` somewhere on their first line. Emacs-28 gives an orange `/d` warning in the modeline when that line is missing (and uses a discrete `/l` instead when the line is present). And you can click on the `/d` to fix the problem. Stefan
