[PHP-BUG] Req #70413 [NEW]: FR: support to new() keyword

From:             david dot proweb at gmail dot com
Operating system: 
PHP version:      Next Minor Version
Package:          PHP Language Specification
Bug Type:         Feature/Change Request
Bug description:FR: support to new() keyword

Description:
------------
It should works exactly like the `new`, but with some features.

    // Usage.
    new('\User');      === new User;
    new(User::class);  === new User; 
    new($user);        === new $user;

    $user = new(User::class)->find(1); === (new User)->find(1);

    // Arguments.
    new(User::class, 1, 2, 3)  === new User(1, 2, 3);

    // Maybe: use another object to copy directly the name.
    $userClass = new(User::class);
    $userNew = new($userClass);   === $userNew =
new(get_class($userClass));

Signature (pseudo-code):

    function new ($object, ... $args) {
        assert(is_object($object) || is_string($object));
        assert(!is_resource($object));
 
        if (is_object($object)) {
             $objectClass = get_class($object);
             return new $objectClass(... $args);
        }       
        
        return new $object(... $args);
    }
