That is an interesting thought: although, it is something that non-native speakers struggle with when learning a new language. I wonder if that is a factor when learning a new computer language/concept too.

I suspect it is also related to the Curse of Knowledge (https://en.wikipedia.org/wiki/Curse_of_knowledge). Once you are past the hurdle of initially learning a concept it makes it hard to imagine not being able to grasp it: especially when dealing with abstract concepts such as scopes.

Exactly what I was trying to express (the Curse of knowledge), thank you for bringing it up, wasn't aware of the phrase.
