Python defines ``pow(0, 0)`` and ``0 ** 0`` to be ``1``, as is common for
programming languages.

The numeric literals accepted include the digits ``0`` to ``9`` or any
Unicode equivalent (code points with the ``Nd`` property).
See http://www.unicode.org/Public/6.0.0/ucd/extracted/DerivedNumericType.txt
