example in the section 'Clone to stasify borrow checker' may deprecated due to NLL

[mokurin000]

// define any variable
let mut x = 5;
// Borrow `x` -- but clone it first
let y = &mut (x.clone());
// perform some action on the borrow to prevent rust from optimizing this
//out of existence
*y += 1;
// without the x.clone() two lines prior, this line would fail on compile as
// x has been borrowed
// thanks to x.clone(), x was never borrowed, and this line will run.
println!("{}", x);

the println! could work due to NLL even if there is no clone() call, to solve this, *y += 1; should be placed under println!, so at the println line, y lives

Deperated?

Deperated

Sorry , I mean, deprecated

Wouldn't the behavior be different, printing 5 with clone and 6 without?

behavior will not change, so actually only this line will run. needs change
