Whether it's name or to_name, he is seeking a way to differentiate
person names and Nonlinear Altitude Modulation Expositors.

To use an example from your book, he wants to distinguish
between Action#sin and Trig#sin.  He can "let it ride" and see
what happens by just calling #sin, but I think the motivation
behind these threads is to provide support for methods/interfaces
which claim some conformant behavior.
