  If you need a byte string literal under Python 2 and a unicode string literal
  under Python 3, use the :func:`str` builtin::
  
      str('my string')
  
  In Python 3, there aren't any automatic conversions between ``str`` and
  ``bytes``, and the :mod:`codecs` module became more strict. :meth:`str.encode`

little use for that method, because they hardly ever deal with
``bytes``.)
