Flag a dereference to a pointer to a container aspect that will happen to be invalidated by dereference

As far as we will notify, these procedures cause code that performs as this article well or better than older, extra conventional approaches; they are meant to follow the zero-overhead basic principle (“Whatever you don’t use, you don’t buy” or “when you use an abstraction system appropriately, you can get at the very least pretty much as good performance as in the event you had handcoded making use of decreased-level language constructs”).
