      special case is added here:  passing a negative number selects the
      highest protocol version supported by a particular implementation.
!     This works in previous Python versions, too, and so can be used to

!     HIGHEST_PROTOCOL is supplied by both pickle and cPickle, equal to
!     the highest protocol number the module can read.  This is cleaner
!     than passing -1, but cannot be used before Python 2.3.
