Description:
------------
When referencing a class constant, as of PHP 5.3.0, it's possible to reference the 
class using a variable, e.g. "$myObj::MY_CONST".

It's not possible however to use that syntax with object properties, e.g. 
"$anotherObj->myObj::MY_CONST". I think that's inconsistent.

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

class MyClass {

   const MY_CONST = 'foo';

}

$myObj = new MyClass();

// Works, prints "foo"
// echo $myObj::MY_CONST;

$anotherObj = new stdObject();
$anotherObj->myObj = $myObj;

// Raises a parse error
echo $anotherObj->myObj::MY_CONST;

Expected result:
----------------
Prints "foo"

Actual result:
--------------
Raises "Parse error: syntax error, unexpected '::' (T_PAAMAYIM_NEKUDOTAYIM), 
expecting ',' or ';'"
