Description:
------------
The following file namespace declaration:

namespace \Name;

Does not give a Parse Error. It's sister declaration:

namespace \Name {}

does.


Test script:
---------------
<?php
namespace \Name;


Expected result:
----------------
Parse Error in Line 2 about an unexpected ; or T_NAMESPACE_SEPARATOR

Actual result:
--------------
Parser has no problem with the file at all.

Problems become only noticeable at runtime then.
