> Citation needed. I would expect a rewrite guided by an existing implementation (not the same thing as a rewrite aimed at achieving a from-scratch redesign) to result in fewer bugs as it would effectively be equivalent to a full code review, and that's before we take into account the difference-of-language effects. Humans are fallible. Rewriting the code introduces the possibility that the human coding it might make a mistake. This is true even when using existing code as a guide.
