The reason for this is that I'm right despite this happens to contradict all kinds of 'established opinions'. But please feel free to point out any why I'm wrong, instead of just asserting that I certainly must be. Eg, is it wrong that - mathematically - 'optimization' refers to 'finding the best [optimal] solution' but that so-called 'compiler optimization' doesn't yield 'optimal solutions'?
