Suggest new operator like with in c#

Hello

As i read in https://wiki.php.net/rfc/howto write here “concept”.

For fill dto and other same objects need assign to many fields of on
object, before properties was be use return $this  in setters and code
loos like this

$item
    ->setType(Item::TYPE_CLOUT)
    ->setProduct($product)
    ->setPrice($price)

and it was single operator, but it not work with simple property or
get-set function need write

$item->type = Item::TYPE_CLOUT;
$item->product = $product;
$item->price = $price;

suggest add operator like with in c# which do action and back context
back and use for example :>
same assign will be look like this

$item
    :>type = Item::TYPE_CLOUT
    :>product = $product
    :>price = $price
;

These days, such objects usually have promoted properties in their constructor, and we have named arguments, which allows this already:

readonly class Item {
public function __construct(
public int $type,
public Product $product,
public float $price,
) {}
}

$item = new Item(
type: Item::TYPE_CLOUT,
product: $product,
price: $price
);

In what way is that insufficient? True it only works on the constructor, but commonly such objects are only assigned to in the constructor.

I imagine this is desirable when one moves away from defining setters
and uses property hooks instead.
