Who asked for a subset?

This is entirely negating the point of Common-Lisp and the `cl' package.

I  don't use Microsoft-Word  because I  don't want  to be  locked into
their proprietary file format.

By the same token, as much as possible, I don't want to be locked into
emacs lisp specificisms.

Everytime  there is  an  emacs  function that  have  an equivalent  in
Common-Lisp, I'll use the Common-Lisp  version.  This gives me the big
bonus to be able to use most  of my lisp code programmed on emacs also
on any other lisp environment.

But I  guess that this gives the  same cold sweat to  Stallman than to
Gates,  to  see that  some  users  of his  programs  may  want to  use
concurent programs!   What if  suddently GNUS or  VM or Kiwi  could be
compiled and used with cmucl or clisp?  Horror!


I don't mind if features specific  to the emacs editor are hard linked
to it  (instead of, for example,  being programmed as  a nice portable
Common-Lisp package).  There may  have valid technical reasons for it,
or I could even  agree with their moral reasons for it.   But if I use
emacs for  prototyping lisp  code, for scripting,  or even  to program
some  personal interactive  tools, why  should they  and all  the lisp
libraries I write be locked to emacs lisp?



If emacs developers are worried by name clashes, what are they waiting
for implementing Common-Lisp packages?

Do not adjust your mind, there is a fault in reality.
