Hum, today str8 is between bytes and str types. str8 has more methods (eg.
lower()) than bytes, its behaviour is different in comparaison (b'a' != 'a'
but str8('a') == 'a') and issubclass(str8, basestring) is True.
I think that a frozenbytes type is required for backward compatibility (in
Python 2.x, "a" is immutable). Eg. use bytes as key for a dictionary (looks
to be needed in re and dbm modules).
