It would be ill-mannered simply to remove these names. > They should be marked as obsolete, perhaps. See my reply to Artur/Bruce. I meant only that the `cl-' versions are not needed. We should definitely not remove the c[ad]\{3,4\}r. If there are already "lots of" cl-c[ad]\{3,4\}r in the field, then that would be too bad. But I doubt that that is the case. Occurrences of such barbarities would, I expect, represent only the exceptional overzealous, early-adopter, conversion of *existing* c[ad]\{3,4\}r. The 56 uses in the Emacs sources are in fact a case in point. Who would write (cl-cadddr (cl-cdar x)) in new code? =20 And even if it is case that there are "lots of" such occurrences out there, we should just apologize for our recent-past silliness, redefine the cl-c[ad]\{3,4\}r as temporary (only) aliases for c[ad]\{3,4\}r, deprecate those aliases, and remove them as soon as possible thereafter. I would be quite surprised if there are really a lot of cl-c[ad]\{3,4\}r out there. But there are no doubt lots of c[ad]\{3,4\}r out there.
