error[E0506]: cannot assign to `*x` because it is borrowed
  --> $DIR/issue-75785-confusing-named-region.rs:9:5
   |
LL | pub async fn async_fn(x: &mut i32) -> (&i32, &i32) {
   |                          - let's call the lifetime of this reference `'1`
LL |     let y = &*x;
   |             --- `*x` is borrowed here
LL |     *x += 1;
   |     ^^^^^^^ `*x` is assigned to here but it was already borrowed
LL |     (&32, y)
   |     -------- returning this value requires that `*x` is borrowed for `'1`
