Hi Rob,


On the abstractness of the examples: I can live with the choice that you've explained to me already a couple of weeks. I may ask to re-consider it as a whole, when the "Primer/tutorial" comes out and fulfills the need (or not). But it is not my point right now. It's more about not keeping to a strict approach to whatever option your generally pursue. Even if trying to be abstract in general, for some specific cases it may still be good to be flexible and not stick to abstract labels/identifiers. Which is why I'm flagging such specific cases in my reviews.
