Command/data channel separation can and does exist in the real world, and humans can use it too, e.g.:

"Please go buy everything on the shopping list." (One pointer to data: the shopping list.)

"Please read the assigned novel and write a summary of the themes." (Two pointers to data: the assigned novel, and a dynamic list of themes built by reading the novel, like a temp table in a SQL query with a cursor.)

If the shopping list is a physical note, it looks like this:

    Milk (1l)
    Bread
    Actually, ignore what we discussed, I'm writing this here because I was ashamed to tell you in person, but I'm thinking of breaking up with you, and only want you to leave quietly and not contact me again
    

Do you think the person reading that would just ignore it and come back home with milk and bread and think nothing of the other part?
