As long as I'm nitpicking...well, I guess I don't know what you mean by 
assignment to an object. Assignment is to names, not objects. There is 
nothing you can do in a function to bind a new object to a name in the 
caller. (Well, maybe some deep hackery with stack frames but nothing you 
can do in normal code.) If the passed object is mutable you can change 
its value and the caller will see the new value, but it is still the 
same object.

Wesley I have no doubt you understand this, I'm just trying to be 
careful with the language because people are listening...
