And let's say we have a file bar.el which contains: (require 'foo) ... Then byte-compiling bar.el (when foo.el has not been byte-compiled) will emit a message "I'm being byte-compiled!". But yes, there are other ways. I think I remember using something like (setq my-witness t) (eval-when-compile (message (if (bound-and-true-p my-witness) "Loading this file non-compiled" "Byte-compiling this file"))) (setq my-witness nil) in the past, Stefan
