[[Creating a reference to a variable is called borrowing]]


---

When we assign a Box to a name we say that name owns the box. Any time we copy the pointer to that box to another name we also pass ownership to that name.

After we pass ownership and move into a new scope the original variable is freed. Thus when we return to the original scope it is no longer possible to use it.
