OK, I understand that using 'latin1' is just a hack and not Pythonic way.

Then, I hope bytes has a fast and efficient "format" method like:
>>> b'{0} {1}'.format(23, b'foo')  # accepts int, float, bytes, bool, None
23 foo
>>> b'{0}'.format('foo')  # raises TypeError for other types.
TypeError

And line buffering in binary mode is also nice.
