More important, said person would also understand sooner or later (or be told) that the term "pass by reference" doesn't have anything to do with C++ references at all. It exists to describe the act of passing a value indirectly through an indicator value. And armed with this knowledge would cease their opinion and go "aha! That explains it then. My opinion doesn't make sense then"
But not in this case. Said opinion is kept, thrown at every other opportunity, and completely ignores maybe(?) the last 50 years of computing science. So yeah! Who the hell is she to have an opinion on this matter, may I ask?
