I'm not sure what distinction you're referring to, can you explain?

Obviously there is a syntax difference between x.attr and x['key'], but
attributes *are* items in a dictionary (ignoring __slots__ and __getattr__
for the time being). Either the instance __dict__, the class __dict__, or a
superclass __dict__.
