Because I don't know what to give to the second arg FORM of
'macroexp--warn-and-return'. I tried to use 'name' for FORM,
but then it prints some irrelevant warning:
mh-e/mh-speed.el:161:25: Warning: reference to free variable `mh-speed-toggle'
But with this patch that uses `byte-compile-warn`:
diff --git a/lisp/emacs-lisp/byte-run.el b/lisp/emacs-lisp/byte-run.el
index 0f8dd5a284..bf9f3f3fbc 100644

decls))
(def (list 'defalias
(list 'quote name)
these warnings finally look right:
ELC mh-e/mh-speed.elc
In toplevel form:
mh-e/mh-speed.el:161:25: Warning: Unknown defun property `ignore' in
mh-speed-toggle
mh-e/mh-speed.el:179:9: Warning: Unknown defun property `ignore' in
