(Very simple) Warn Should the return value of new or possibly a perform call with an operator return benefit is assigned into a raw pointer or non-owner reference.
Code using a library may be much simpler to write than code Doing the job immediately with language functions, Considerably shorter, are usually of a better volume of abstraction, along with the library code is presumably now analyzed.
