Yes, I&#x27;ve used Go. The compiler is fast and that&#x27;s really nice; fast compilation was one of their explicit goals.<p>Pascal and C are fast because they&#x27;re old and relatively simple, and their implementations are mature.<p>C++ becomes super slow when you start doing anything interesting, when I tried Rust it seemed very slow, even Java is slow although it seems like it shouldn&#x27;t have to be. Those languages are all more widely used than D, I think.<p>[edit: typo]
