I presume that this argument is obsolete :) ) I've long been an advocate of dumping cl with Emacs; XEmacs does so without problems. CLisms simply result in cleaner, smaller code than one can write using nothing but elisp primitives. The latest objection is that dumping CL would Emacs would increase the size of the printed and bound Emacs Lisp Reference Manual from the FSF. I find this objection unconvincing because it applies to _any_ new feature, and I don't think we're against adding new features to Emacs.
