Why is this way of solving the challenge:

`fn main() {
let y: Option = Some(Point { x: 100, y: 200 });

match y {
    Some(ref p) => println!("Co-ordinates are {},{} ", p.x, p.y),
    _ => panic!("no match!"),
}
y; // Fix without deleting this line.

}`

more preferred than this one:
`fn main() {
let y: Option = Some(Point { x: 100, y: 200 });

match &y {
    Some(p) => println!("Co-ordinates are {},{} ", p.x, p.y),
    _ => panic!("no match!"),
}
y; // Fix without deleting this line.

}`
