expected output:

5 Method A::x() return type has no value type specified in iterable type array.
5 Method class@anonymous/tmp.php:16::x() return type has no value type specified in iterable type array.
-5 Method class@anonymous/tmp.php:21::x() return type has no value type specified in iterable type array.
+5 Method stdClass@anonymous/tmp.php:21::x() return type has no value type specified in iterable type array.When an anonymous class name is dumped, parent class name like stdClass@anonymous should be dumped instead of class@anonymous.
