  The function name, within a function, is just a pointer to a location in
memory. When something is assigned to the function name variable, it is loaded
into that location. When a return statement is executed, the value in that
location is the function returned value. Thus, the *last* value assigned
to the function name variable before execution of a return statement is
the returned value.
