Lisp-1 means there's one value cell per symbol.  Lisp-2 means there's
two cells, the symbol value and the function value:

   (setq list '(2 3 4))

Sets the symbol value of "list" to "(2 3 4)" in both CL and Scheme.
But in CL, the built-in "list" function doesn't get clobbered.  In
Scheme, it does.
