If they're interned, then that's pretty much true, but symbols aren't
all interned.


PS: And then of course, there are major ugly hacks like:

(let* ((ob (make-vector 10 nil))
       (s1 (intern "a" ob))
       (s2 (intern "b" ob)))
  (setf (aref (symbol-name s1) 0) ?b)
  (and (equal (symbol-name s1) (symbol-name s2))
       (not (equal s1 s2))))
