Confusion about rooting in Borrowed Pointers Tutorial.

[nejucomo]

Section 5 Borrowing managed boxes and rooting of the Borrowed Pointers tutorial says:

"A heap box that is unrooted is one such that no pointer values in the heap point to it."

Shouldn't this say:

"A heap box is unrooted if there are no owning (non-borrowed) pointers to it."

?

In the following example, isn't the Point rooted, even though there are "no pointer values in the heap" pointing to it?

fn f() {
  let p = @Point { x: 42, y: 23 };
  let y = &p.x
  // ...
}

This whole section is gone, since managed boxes are. It can be closed.
