Understand that a Mutator calling another (earlier) Mutator carries all the
stipulations of the former one. That is our particular way to save time and
space (gravely admonished by Smith), in developing multiple variants,
rather than to rewrite whole Rules-sets with only one or two changes. For
example, the latter is farcically done after year 2000 within twenty-odd
Carrera-Capablanca '8x10's. Our method of calling is used instead in
comments at ''91.5 Trillion...'' also. Betza perhaps originates the
efficiency with his ''Rule-Zero'' for 8x8.
