    # The boolean type.  Unfortunately, ruby doesn't have a clear cut
    # boolean primitive (it has `TrueClass` and `FalseClass`, but no
    # `Boolean` class), so we set the primitive to nil to prevent
    # odd stuff from happening.  It can still be matched by other
    # values.
    class Boolean < Object

      options[:primitive] = nil
