Description:
------------
Following the strong typing in the class description, I expect that when casting an object to an array, the array will match the described types or throw an exception.

In this example, I also have a property ($typeString) that cannot be null. I skipped the initialization of this property in the code and expected that when I tried to transform such an object to an array, I would get an exception like Typed property ... must not be accessed before initialization, as if I access an uninitialized property.

I think if the property is in a typed class, then casting to an array should take into account typing.

Test script:
---------------
class A 
 {
     public int $typeNumber;
     public string $typeString;
 }
 
 $a = new A();
 $a->typeNumber = 1;
 var_dump(
     (array)$a
 );

Expected result:
----------------
Uncaught Error: Typed property A::$typeString must not be accessed before initialization

Actual result:
--------------
array(1) {
  ["typeNumber"]=>
  int(1)
}
