They aren't the same for object references. The reference can't be changed, but the properties can.


Depends on the language. In C++

  const std::vector<int>& foo = bar.GetVector();
foo is a constant object reference cannot have its properties changed (and also cannot be changed to refer to a new object).

  std::vector<int>& foo = bar.GetVector();
Is an object reference that can have its properties changed (but cannot be changed to refer to a new object).
