So far as we could convey to, these principles bring on code that performs at the same time or a lot better than more mature, much more conventional methods; they are meant to Stick to the zero-overhead principle (“what you don’t use, you don’t pay for” or “if you use an abstraction system properly, you receive at the least nearly as good overall performance as should you experienced handcoded applying reduce-amount language constructs”).
