I didn't do the `%` interpolation yet as it is very complicated, and so far
not very important as there shouldn't be much any code using it yet, so it
is not very important for testing in early phases. Unfortunately the
formatting language differs from thestr language. And there still is no
`.format` and afaik will not be:

    >>> bytearray(b'123%b') % b'foo'
    bytearray(b'123foo')
    >>> b'123%b' % b'foo'
    b'123foo'
    >>> b'123%b'.format
    Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
    AttributeError: 'bytes' object has no attribute 'format'
