"""
This module redefines ``str`` on Python 2.x to be a subclass of the Py2
``unicode`` type that behaves like the Python 3.x ``str``.

The main differences between ``newstr`` and Python 2.x's ``unicode`` type are
the stricter type-checking and absence of a `u''` prefix in the representation.

It is designed to be used together with the ``unicode_literals`` import
as follows:

>>> from __future__ import unicode_literals
    >>> from builtins import str, isinstance

On Python 3.x and normally on Python 2.x, these expressions hold

>>> str('blah') is 'blah'
    True
    >>> isinstance('blah', str)
    True

However, on Python 2.x, with this import:

>>> from __future__ import unicode_literals

the same expressions are False:

>>> str('blah') is 'blah'
    False
    >>> isinstance('blah', str)
    False

This module is designed to be imported together with ``unicode_literals`` on
Python 2 to bring the meaning of ``str`` back into alignment with unprefixed
string literals (i.e. ``unicode`` subclasses).

Note that ``str()`` (and ``print()``) would then normally call the
``__unicode__`` method on objects in Python 2. To define string
representations of your objects portably across Py3 and Py2, use the
:func:`python_2_unicode_compatible` decorator in  :mod:`future.utils`.
