I understand and not that I need it. Then if the Emacs Lisp `defun'
does not support &key, why is then this below working?
(defun tmp-function-1 (text html &key one)
"This one works fine"
(message one))
(tmp-function-1 "text" "<html>" :one "Hello")
It should not work, if Emacs Lisp does not support &key
Isn't it?
