Description:
------------
When creating a new object reference with variables and namespaces (tested with aliasing namespaces [use namespace as alias] and not [\long\namespace\path]) and it fails in both scenarios.

This works without the use of namespaces. This bug seems like an overlooked feature.

Test script:
---------------
# test.php
<?php
use Test as T;
require "namespace_test.php";
$name = "MyClass";
$obj = new T\$name;
?>

# namespace_test.php
<?php
namespace Test {
    class MyClass {
	function __construct() {
	    echo "Testing!";
	}
    }
}
?>

Expected result:
----------------
Testing!

Actual result:
--------------
Parse error: syntax error, unexpected T_VARIABLE, expecting T_STRING in test.php on line 5
