Re: emacs lisp syntax rfc: (cond (EXPR => (lambda (X) ...)))

    I should clarify.  The original proposal should read:

      (cond (EXPR => 1-ARY-FUNC) ...)

It would rarely be useful, so it is not worth adding to Emacs Lisp.

        ((cdr list) => #'car)
        ((car list) => #'car)

That would be possible when the computation to be done
happens to match an existing function.  That was true in my
(artificial) example, but it is rarely true in real life.
