The purpose of the `cl-' prefix is so that we don't need to describe those Common Lisp functions in the manual. That is for functions whose reason for existence in Emacs Lisp is compatibility. When a function exists for other reasons, we should describe it in the Emacs Lisp Reference Manual so that users can find it. Giving it the`cl-' prefix is unnecessary and confusing. Let's define it without a prefix. -- Dr Richard Stallman (https://stallman.org) Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
