In the context of bug#37034, some initial support for CL functions and
methods was added to checkdoc.  On my code, the changes make checkdoc
trigger warnings on perfectly valid code IMO. For example,

  (cl-defmethod foo ((a list)) "Return A.")

Checkdoc complains that LIST should be described. I disagree with that,
list is a type, not a argument name.

I attach to this bug report a patch introducing test cases to
checkdoc-tests.el. If it's not possible to implement full support for CL
I prefer that checkdoc doesn't complain even if there is a bug in the
docstring rather than checkdoc complains when the docstring is correct.

Best,
