Amen to that. I edit the code of others on a daily basis, and I'd have to agree completely. High level languages are expressive for a reason, and using clear variable names and code formats can easily speed things up. Our computers these days are incredibly fast, and come supplied with a considerable amount of memory, and while there do exist situations where that isn't the case it has still largely become the norm. There is no reason we can't optimize our code style for readability and for performance at the same time. I dare say that's ultimately what all developers should strive for.
