Lexical binding means you can figure out for each occurrence of a
name, its binding form.  Consider this (probably not exactly
CL-correct, but you'll get my drift, I hope):

(let ((foo 23))
  (let ((name 'foo))
    (let ((foo 42))
      (set name -1)))
  foo)

At the place 'foo occurs, there's no way to tell what binding it's
associated with.  In fact, it may be associated with several different
bindings at run time, which is a hallmark property of dynamic binding.
