I have a similar hack here for the same reason ;-) So a +1 from me (tho I'd recommend using the `debugger-` namespace rather than `early-`). > So, how about including this file in Emacs, amending eval.c to use it if > backtrace.el isn't yet avaiable? Comments and criticism are welcome. I don't see any need for a change to `eval.c`. Just put the (setq debugger #'early-debug) and (setq debugger #'debug) at the appropriate places inside `loadup.el`.
