> “the other parts” of C++ I agree and that would be great. I'd also love a place to learn design with feedback. Should I use a friend function? Free function? Separate class? Abstract class? Should I create a separate folder and start a module? It would be great to have something where you try an implementation, get feedback, and try again maybe a few times and then are presented with a few ideal options that you might not have tried.
