I forgot to mention that this problem is not about
SHADOWING at all, it is about BINDING.  Shadowing (of
symbols) is an altogether different and confusing area of
CL.  Shadowing is the means by which you define a symbol
in a package to be different from a symbol that that
symbol might otherwise acquire through using another
package.  For instance:

(defpackage foo (:Use lisp))

(shadow '(nil) 'foo)

(eq nil foo::nil) -> nil

Most people don't have to do this sort of thing.
