If you can't use SimpleNamespace (eg you need to support pre-3.3), the
easiest way is an empty class:

class SimpleNamespace(object): pass

This will work in all versions of Python back to... I dunno,
2.something, maybe 1.x. Or, of course, you could lift the pure-Python
definition of SimpleNamespace from the docs and use that :)
