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:
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?
