Even prefixed functions and symbols can conflict with something the user
has specified; the likelihood is just lower. In general, CL symbols,
even without a namespace qualification, won't cause problems because cl
is *already* so widely-used that anything that would conflict with it
has already been fixed.

Can you provide a real example of something that would break if cl.el
were dumped with Emacs?
