Has anyone found the need to declare the return parameter of a copy assignment operator const?

The copy assignment operator has the usual signature:

    my_class & operator = (my_class const & rhs);

Does the following signature have any practical use?

    my_class const & operator = (my_class const & rhs);

You can only define one or the other, but not both.
