Actually, this will work! In the "class_name_reference" rule, the
"zend_do_fetch_class" function is called. Inside this function, class_name
is a znode, and what is assigned to the opcode is "opline->op2 =
*class_name". This function is changed to check the import hashtable, and if
a match is found, then the znode string value is updated to contain the full
class name! Here's some pseudocode:

<?php
include('Object.php');
// include opcode is generated here

import lang:Object;
// "Object" => "lang:Object" added to import hashtable

$o = new Object();
// zend_do_fetch_class checks for "Object" in the import hashtable.
// A match is found, so "class_name->u.constant.value.str" is modified from
"Object" to "lang:Object".
// At runtime, the lang:Object class will be created and added to
class_table,
// and since all opcodes are using lang:Object instead of simply Object,
then everything will work.
