Sorry, I mean making Namespace subscriptable.  eg:

>>> v = argparse.Namespace(abc = 123)
>>> v
Namespace(abc=123)
>>> v.abc
123
>>> v['abc']
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'Namespace' object is not subscriptable

> add_argument('foo_bar', metavar='foo-bar', ...)

This works. Thanks!

Cheers,
Joe
