No, C++ is particularly well suited to that since it's possible to implement those with zero (and in practice less than zero) overhead. The problem is overridable functions; i.e. not generic implementations that work on various structures by compiler specialization, but methods on classes whose implementation varies at runtime by dynamic dispatch. E.g. a getLayoutWidth method with a different implementation for blocks and inline runs, and where it's possible to call the implementation without knowing at compile time which it is. Those cost performance. |
