Description:
------------
I have been going through 3v4l.org submitted scripts to find anomalies in 5.6.0-beta2; and I found http://3v4l.org/8Yl8V where the parser accepts an Array as class-constant; but when using that constant you still get a fatal error. This seems incorrect.

Here you see 5.6.0-beta2 incorrectly doesn't generate a fatal error: http://3v4l.org/8Yl8V
Here you see it does generate an error when using the const: http://3v4l.org/LG2EM

Test script:
---------------
<?php

interface exampleInterface
{
    const _TYPE = array(
        "name1" => "0",
        "name2" => "1",
        "name3" => "2"
    );

    public function x();
}
// Uncommenting this shows a Fatal error; but it should be show regardless
//class A implements exampleInterface { public function x(){var_dump(self::_TYPE);}}$a = new A;$a->x();

Expected result:
----------------
Fatal error: Arrays are not allowed in constants at run-time in /in/LG2EM on line 19

Process exited with code 255.

Actual result:
--------------
""
