So far as we will tell, these rules cause code that performs at the same time or much better than older, more traditional techniques; they are supposed to Adhere to the zero-overhead basic principle (“Whatever you don’t use, you don’t pay for” or “after you use an abstraction system appropriately, you have at the least nearly as good general performance as in the event you experienced handcoded applying reduced-level language constructs”).
