The context was about whether rote learning was helpful, and I read your comment as suggesting that it was - not just that background knowledge helps but that rote learning without understanding can help someone gain understanding later. By asking about Anki flashcards I was wondering what someone might rote memorise without understanding which would then help with learning about that programming sentence (I can't quickly think of anything but maybe you had something in mind).

And I'm also saying that rote learning and background knowledge can hinder progress and require time unlearning, like the beginner needs to spend time learning. e.g. a mathematical sequence like "even numbers" can be infinitely long and the sentence probably doesn't mean that strings can have infinite characters in them. I guess, if you don't know the meaning of the words the sentence doesn't help you, if you know the words from a different context but don't know the programming language then the words don't help you, and if you already know the language then the words add nothing for you. Learning is impossible, Q.E.D ;-)
