We need a (require 'cl-<something>) which brings up CL but only within
the "cl-" namespace.  I don't have a good idea for naming.  `cl-defs'
might be OK, but I'm open to other suggestions.  Maybe `cl-layer', or
`cl-emu', or `cl-compat'?

`cl-funs' is another option, indeed.

No: The way to do it is to rename cl.el to cl-<something>.el, change all
its definitions to use the "cl-" prefix and then create a new cl.el
which only contains defaliases.
