I'm struggling to understand how to make functions defined with
cl-defgeneric interactive:
(require 'cl-lib)
(cl-defgeneric my/test ()
(interactive)
(message "generic"))
If you evaluate that you can do M-x my/test, as expected. However, as
soon as you evaluate this:
(cl-defgeneric my/test (&context (major-mode emacs-lisp-mode))
(interactive)
(message "method"))
M-x my/test no longer works.
Is this a bug or am I misunderstanding how this works?
Thanks,
Alex

Done.
