What my job is has no bearing on whether arguments about which definition of a term is right are interesting or not. Such arguments are always uninteresting. It is the semantics behind them that are interesting. I keep focusing on the semantics and you keep arguing about the defintions. So far you have not said anything of interest. Although you have amply demonstrated my earlier point, which is that people get unbalanced when you point out that return values are not affected by writing to global variabes.
