Well, but aside from that one thing, people need to keep in mind that D
is not dynamic/interpreted/VMed, and does have full low-level
capabilities. Those are the things that make C fast, and D shares them.
Plus modern C codegen also makes things fast, but D generally uses C
backends, so again D shares that, too.
