@futurebird maybe even just a “it doesn’t need to compile right now, we’re focused on <concept>” and leaving the compiler angry

@futurebird I’ve mostly taught adults, so this might not work for you, but I would try explaining that at the end of the lecture, you don’t need them to have working code, you need them to have a working understanding. They’re missing the important part of class, the learning, to focus on an unimportant part of class, producing a working program. If it’s not working, focus up and wait until we have a pause. To me, this sounds more like an etiquette question than a programming one.
