OK, let's try it:
>>> c = {}
>>> c["x"] = 3
>>> c.x = 4
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'dict' object has no attribute 'x'
>>> class AttrDict:
... def __getitem__(self, key):
... return getattr(self, key)
...
>>> c.x = 4
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'dict' object has no attribute 'x'
