Passing a property by reference allows the data aspect of the object to be manipulated without communication with the object itself. That's why I said "as it should be."

You are right, if parameter passing link to outside from the object.
But what if the object itself want to manipulate on its own property in one of its method, like:

this.property=upper(this.property)
