[[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.

[[Passing a pointer to heap data as an argument to a function transfers its ownership]]
