1. It is useful sometimes, for example consider a program accepting input in the form of templates. An input of `"Value: {obj.field}"` is more readable than `"Value: {obj['field']}"`.
- Such an example is an app processing JSON and evaluating expressions on it, like `jq` or a similar Python app, [`pjy`](https://pypi.org/project/pjy/): `pjy d.item.subitem` instead of `pjy "d['item']['subitem']"`
2. There are other ways to do it:
- Subclass dict and implement `def __getattr__(self, attr): return self[attr]`
- Use `self.__dict__` instead of `self._dictionary`
