        Does anyone know if Scheme is defined such that ANY binding can be
   changed or is there some set of functions/identifiers that can be (or
   MUST be) prevented from being re-defined?

        For instance --- are you able to do blatantly stupid things like:

                        (define car  5)

    or are such things verbotten?  If this sort of thing isn't allowable, is
    there some list of identifiers which can't be re-defined?
