Description:
------------
Example show: $ao don't have public properties, object not implements method __get, but "magic" still work.

Test script:
---------------
<?php
$ao = new ArrayObject(['foo' => 'bar'], ArrayObject::ARRAY_AS_PROPS);
var_dump(get_object_vars($ao));
// []
var_dump(method_exists($ao, '__get'));
// false
var_dump($ao->foo);
// "bar"
?>

Expected result:
----------------
Test object $ao must have public property "foo" or implements magic methods(__get, __set", __isset, __unset) to overloading that property.

Actual result:
--------------
get_object_vars($ao); // []
method_exists($ao, '__get'); // false
$ao->foo; // "bar"

Internal objects do not need to implement the magic functions,
because there are other mechanisms available. If you want to check
whether a certain property is set, use isset();
<https://3v4l.org/6emoD> looks fined to me.

cmb@php.net "other mechanisms available"
I'm know, but it's:
1.not reflectable
2.unexpected results of function calls
3.created problems at extending class

Okay, it may be an option to change the implementation in the next
minor or major release.  However, that requires discussion which
is beyond the scope of this bug tracker (there are several other
internal classes which behave similar).  Therefore, please write
mail to the internals mailing list[1].  For the time being, I'm
suspending this ticket.
