Description:
------------
Constants defined inside classes can be defined as an array prepopulated with key, value pairs; however this data is not directly accessible.

It is possible to create a local variable copy of the constant at runtime and use it to access the data.

If class constants are not meant to be able to hold array data, then a parse error should of been thrown on the 'const' declaration.

Reproduce code:
---------------
class test {
  const someData = array('foo' => 'bar');

  function __construct() {
    $dataCopy = someData;
    print($dataCopy['foo']);  // This works
    print(var_dump(someData));  // This works (shows all array information)
    print(someData['foo']);  // This throws a parse error
  }

}

$obj = new test();

Expected result:
----------------
bar
bar
bar

.. Jackpot! :)

Actual result:
--------------
Parse error: parse error, unexpected '['
