 Anyway, back to our example. Since this memory is on the heap, it can stay
 alive longer than the function which allocates the box. In this case, however,
 it doesn’t.[^moving] When the function is over, we need to free the stack frame

 implementation of `Drop` for `Box` deallocates the memory that was allocated
 when it was created. Great! So when `x` goes away, it first frees the memory
