Oh, I wasn't trying to make a claim that this would result in any noticeable performance degradation in the vast majority of cases, but as a means of making code more understandable this particular example suffers in comparison to a comment: less code is on the screen, it requires the reader's eye to jump elsewhere, and again that particular expression is simple and about as easily understood as the function name that replaced it. I think we agree on what to prioritize in writing code, but I don't think that example in the article was a good demonstration of those priorities in practice.
