If you want to add this, see https://wiki.php.net/rfc/howto

If you need an inline type assertion, you can use something like the following 
pattern:

class MyClass
{
  public static function cast(MyClass $obj)
  {
    return $obj;
  }
}

Then you have a MyClass "cast" or type assertion via:

  $x = MyClass::cast($x); // this will throw if $x is not an instanceof MyClass
