Reminds me of glom[1], another Python library that allows for traversing dicts using dot notation.

  >>> data = {'a': {'b': {'c': 'd'}}}
  >>> glom(data, 'a.b.c')
  'd'

Box uses a slightly different approach.

  >>> data = Box({'a': {'b': {'c': 'd'}}})
  >>> data.a.b.c
  'd'

I didn't see anything in the README about type inference, which would make the later example more desirable in my opinion. Otherwise I would prefer not to introduce a new container class to my code (Box) if avoidable.
