Thanks, I've now fixed the doc string on the emacs-30 release branch
to say that, and I'm therefore closing this bug.

Subject: 29.4; cl-defgeneric docstring is incorrect

[Message part 4 (text/plain, inline)]

The docstring for cl-defgeneric reads:

(cl-defgeneric NAME ARGS [DOC-STRING] [OPTIONS-AND-METHODS...] &rest
DEFAULT-BODY)
[...]
With this implementation the ARGS are currently ignored.
[...]

However, this is not the case, as seen in this excerpt from an ielm buffer:

ELISP> (cl-defgeneric foo (x y) (+ x y))
foo
ELISP> (foo 1 2)
3 (#o3, #x3, ?\C-c)
