Why is that? Mmhh, I think is because of this from loadup.el: ==== (load "emacs-lisp/macroexp") (if (byte-code-function-p (symbol-function 'macroexpand-all)) nil ;; Since loaddefs is not yet loaded, macroexp's uses of pcase will simply ;; fail until pcase is explicitly loaded. This also means that we have to ;; disable eager macro-expansion while loading pcase. (let ((macroexp--pending-eager-loads '(skip))) (load "emacs-lisp/pcase")) ;; Re-load macroexp so as to eagerly macro-expand its uses of pcase. (let ((max-lisp-eval-depth (* 2 max-lisp-eval-depth))) (load "emacs-lisp/macroexp"))) ==== > need to preload pcase? I fear I don't have an answer as ATM I don't uderstand why it should be different compared to master. Andrea
