Description:
------------
I think empty($expression) is supposed to evaluate $expression before it checks if it is empty.

In the code bellow, empty($obj->protectedProperty) is supposed to call __get before checking if it's empty. That makes sense, right? Well, I don't think it's happening.

Sorry if I am missing something. But I think this behavior should change.

Test script:
---------------
$fooList = [
    new Foo,
    new Foo
];

$bar = new Bar($fooList);

var_dump(empty($bar->fooList)); // true

$fooList = $bar->fooList;
var_dump(empty($fooList)); // false

class Foo { }

class Bar
{
	protected $fooList = [];

	public function __construct(array $fooList)
	{
		$this->fooList = $fooList;
	}

	public function __get(string $property)
	{
		return $this->$property;
	}
}
