There are such amazing multiplicative gains from D's design decisions -- as you describe here, even when you _need_ to drill down and micro-optimize, very often that too can be achieved in a way that is simpler than its C equivalent. And so, at every level of your code, you get that opportunity to focus more on exploration and improvement and less on firefighting.
