That exists for the assignment operator too (which happens to be a 
misnomer).

   lhs = rhs;

may mean, without any user overloading:

a) assign (destroy the value of lhs and copy the value of rhs)

b) let lhs provide access to the same object that rhs is providing 
access to (as a side effect, if lhs was the single reference to lhs's 
object, then the object may be destroyed in the future)

The behavior depends on whether the type is a value type or a reference 
type.
