How would this interact with the foreach-list syntax?

$data = [
    ["id" => 1, "name" => 'Tom'],
    ["id" => 2, "name" => 'Fred'],
];

foreach ($data as ["id" => $id, "name" => $name]) {
    echo "id: $id, name: $name\n";
}

Having something like:
foreach ($data as (int) ["id" => $id, "name" => $name]) {

Would then make both $id and $name integers?
