Do you mean set Vdebugger to > debug-early in syms_of_eval? Yes. > How would that make reloading debug-early.el safe? Because then `debug-early.el` wouldn't have a `setq` at top-level so you could reload it in a normal Emacs session without having the unfortunate side-effect of setting `debugger` back to `debug-early`. IOW it would make `debug-early.el` better follow the convention that loading an ELisp file should have "no" effect. Stefan
