Provides speed-ups to - inverted in/is tests, inverted jumps, while 1 loops, and jumps to - unconditional jumps. - -- Added a new opcode, NOP, which is used in some of the bytecode - transformations. - - int(s, base) sometimes sign-folds hex and oct constants; it only does this when base is 0 and s.strip() starts with a '0'.
