/**********************************************************************

    The following class F compiles, runs, and does exactly what I WANT.

    What I DON'T LIKE about F is:

        1.) Unnecessary enum
        2.) Unnecessary static array of pointers
        3.) High-maintenence coordination of the above two items

    I would LIKE to return the member function pointers directly.
    This looks rather like class G below (in which the self-referential
    nature of the necessary typedef introduces certain nervy concepts
    beyond my learning).
