Useless if you use meaningful names for your variables & attributes.

It may happen that one object attribute refer to an object of the same 
type, but it is quite rare that both can share the same name anyway.

Possible use cases:

1/
car = Car()
car = car.wheel # ???

2/
wheel = Car() # ???
wheel = wheel.wheel # ???

3/
currentCar = Car()
currentCar = currentCar.nextCar

The syntax you prose will be applicable on very little assignements (use 
case 3). I'm not sure it's worth it.
