This can be confused with variables declared with `defconst' - these are
declared constants but it is possible to change their bindings. You are
speaking about self-evaluating symbols like nil and t, right? Because
all symbols are constants, try to change the symbol `foo', there is no
way to change it in any way from Lisp. But you can evaluate it, and the
binding is not always the same, unlike self-evaluating symbols like nil
or :keyword.
Michael.
