Yup.  I've also previously found that section in the *Help* buffer to be
somewhat obscure, so I've made it include the function name, which
should help clarify things slightly (and fixes the problem here as a
side effect, although I guess we could also just bind print-quoted to
nil).

Implementations:

(seq-do function sequence) in ‘seq.el’.

Thanks.

Does the fix still work if a FUNCTION argument is specialized?

(cl-defmethod foobar ((function my-function-type)))
