Honestly, if you are working on a standalone feature with complicated math&#x2F;distributed algorithm&#x2F;transactional concurrency etc. only a handful people in the world understand, how is a code review going to help you beside trivial matters like code formatting&#x2F;naming? How do you approach this situation in order not to upset the few people that can get it done?<p>I remember SUN&#x27;s application servers had a licensed code inside their transactional core nobody was able to understand nor touch; it just worked as it was supposed to, prepared by a single genius who got it right.
