Of course, this sort of thing may leave you gasping in shock and
horror. But look at the bright side. While 128 is a somewhat large
number, it isn't astronomical; I haven't provided for an opcode space
so large that there isn't enough matter in the whole Universe to
print a programmer's manual for the architecture.

Of course, as these many additional sets of instructions get fleshed
out, were the ISA to be implemented, such an ISA would lend new
meaning to the term "dark silicon", since, having so many instructions
available, they could hardly all be in common use.

Indeed, the situation could even be described with the catchy book
title...
