This is why I like to ask people to talk me through a change that I think I don't like, or might be wrong, before passing judgement. One of two things happens in the process of them explaining: - they know something about the context that I was unaware of or have an insight that I hadn't thought of and so I learn something and change my mind - they realise they've missed or misunderstood something, or were unaware of something which I can communicate to them, so they learn something and change their mind. Sometimes this can be as mundane as "this isn't idiomatic, we should prefer the community style. It's almost always a learning experience for one of us, frequently both. I've learnt a lot over the years of reviewing other people's code. In the cases where neither of these things happen it's because it's a question of personal taste, there's nothing wrong with the code, I just wouldn't have written it that way. In those cases I leave it alone.
