No. These rules are exterior the conventional. They are intended to provide the common, and become maintained as existing pointers regarding how to work with The present Common C++ properly. We aim to maintain them in sync Together with the regular as that may be evolved with the committee.

At the highest of the call tree where you get the raw pointer or reference from a smart pointer that keeps the thing alive.

p is really a Shared_ptr, but absolutely nothing about its sharedness is utilised in this article and passing it by price is actually a silent pessimization;
