Confusing Emacs argument parsing with cl-defun
Raw
example.el
(cl-defun wh/foo (arg1 arg2 &key (kwarg1 t))
(list arg1 arg2 kwarg1))
;; We've forgotten arg2, but we get the error:
;; (error "Keyword argument 2 not one of (:kwarg1)")
(wh/foo 1 :kwarg1 2)
;; Instead, it would be clearer to say
;; "Expected a keyword argument (one of (:kwargs1)) but got 1"
