Re: moving more cl seq/mapping support into core

[Richard Stallman]

    _What_ global names? cl.el is _already_ widely used. What symbols
    actually cause a problem _in practice_, _today_?

How would I know?  We're talking about user's own programs here.

The fact that many programmers use cl.el is not conclusive.  Those
programmers won't use cl names for anything else -- others might.

Meanwhile, there is a further issue.  If we move these symbols into
the standard Elisp, we need to document them in the Lisp Reference
manual.  We could certainly do that, with some work.  But it would
also make the Elisp manual bigger and more expensive.
