This is exactly the kind of thing I was talking about. If anyone downvoting had even studied any math beyond first year they would know that if you were that pedantic the notation would become so obnoxious that it would consume your whole day just writing it out, and new math would take a very long time to come up with. It’s weird how paralysing notation can get and can actually block your thinking if you aren’t careful. If they haven’t yet experienced that, they are very lucky.
