Subclassing dict seems like a bad idea. The options value returned by .parse_args() is not supposed to be dict-like, it's supposed to be object-like. That is, the natural way of accessing values from it is through dotted attribute access, not dict-indexing access. All the documentation for the module makes this clear. Giving it both attribute access and dict-indexing access would violate TOOWTDI. The One Obvious way to get dict-indexing access from an attribute oriented object is already vars().
