3. GNU Emacs enforces the backward policy that packages must not use cl.el Common Lisp extensions at runtime. This kind of restriction is another enemy to development momentum; if it's expedient to Vegard or another developer to leverage a standard library, they should be empowered to do so.
But John J. Foerch said in his email of Wed, Oct 3, 2007 at 11:00 PM at http://my-trac.assembla.com/vimpulse/ticket/2 that there are cl.el macros that override core Emacs functions. Do you still stand by your assertion?
Yes. cl.el's version of push subsumes GNU Emacs' standard push - it's not dangerous. Almost anyone who uses Emacs extensively will load cl.el as part of their configuration. XEmacs loads it by default.
What reason does the GNU Emacs team give for this policy? If it turns out to be a flimsy reason, then perhaps you or Vegard could get the policy changed if you wanted to. :)
