"""
Forward-ports of types from Python 2 for use with Python 3:

- ``basestring``: equivalent to ``(str, bytes)`` in ``isinstance`` checks
- ``dict``: with list-producing .keys() etc. methods
- ``str``: bytes-like, but iterating over them doesn't product integers
- ``long``: alias of Py3 int with ``L`` suffix in the ``repr``
- ``unicode``: alias of Py3 str with ``u`` prefix in the ``repr``
