metaclass-boilerplate
=====================
Most Python files should include the following boilerplate at the top of the file, right after the
comment header and ``from __future__ import``:
.. code-block:: python
__metaclass__ = type
Python 2 has "new-style classes" and "old-style classes" whereas Python 3 only has new-style classes.
Adding the ``__metaclass__ = type`` boilerplate makes every class defined in that file into
a new-style class as well.
.. code-block:: python
from __future__ import absolute_import, division, print_function
__metaclass__ = type
class Foo:
# This is a new-style class even on Python 2 because of the __metaclass__
pass
