List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: emacs-devel-bounces+ged-emacs-devel=m.gmane.org@gnu.org Original-Sender: "Emacs-devel" Xref: news.gmane.org gmane.emacs.devel:236920 Archived-At: cl-lib was released 6 years and its uptake has been much more successful than in my wildest dreams. AFAIK it has been technically obsolete already for the last 6 years, in that everything it offers is provided by cl-lib or lexical-binding. I count 6 files in master that still (require 'cl). Of those, 2 only require `cl` conditionally (when running on XEmacs or on Emacs<21), 2 are themselves obsolete (cl-compat and lucid.el), so really there are only 2 packages bundled with Emacs and still actively using `cl`: vhdl-mode and MH-E. So I think Emacs-27 is a good time to declare it officially obsolete (and hence move it to the lisp/obsolete directory). Comments, objections? Stefan
