Implements a lookup table of successive integers using only punctuation operators because alphanumeric keys are “broken,” expressing constants with things like !false then ~ to get 1, left shifts for powers of two, and short arithmetic factorizations for composites; assembles an array of increment results entirely in normal C++ without new syntax. Table length grows logarithmically with token count, fitting roughly base 1.136 per added symbol, a surprisingly small base.
