It depends. If you write your code based on abstractions/class features, does it matter ehat type it is? If I call calculation->execute() I don't care what type of object calculation is as long as it can execute and returns something that'll I'll use later for other purpose. To me auto in this case is something similar to using pointers to a base class, but even more abstract
