Description:
------------
The new per-class constants, introduced in PHP 5, don't allow to access array indizes.
If I define an array as a constant of a class and try to access the first index of this constant for example, the Zend Engine 2 gives a parse error.
Only index access on a variable, that points to this constant, works.

Reproduce code:
---------------
Class Example {
  const CATEGORIES = array('a', 'b');
}

$c=Example::CATEGORIES;
echo $c[0] . "\n";
echo Example::CATEGORIES[1] . "\n";


Expected result:
----------------
a
b


Actual result:
--------------
PHP Parse error:  parse error, unexpected '[' in example.php on line 8
