Description:
------------
After upgradeing from php 5.2.4 to 5.3.2 (with ubuntu 10.4), the following code won't work:

<?PHP

 class namespace extends something {

 }

?>

The error message: PHP Parse error:  syntax error, unexpected T_NAMESPACE, expecting T_STRING in ...

The documentation says: 
Q: If I don't use namespaces, should I care about any of this?
A: No. Namespaces do not affect any existing code in any way
( http://www.php.net/manual/en/language.namespaces.faq.php )



Test script:
---------------
<?PHP

 class namespace extends something {

 }

?>

Expected result:
----------------
in this case, I won't define a php-namespace, but a functionality within my application, which was called so before namespaces existed in php.

Actual result:
--------------
PHP Parse error:  syntax error, unexpected T_NAMESPACE, expecting T_STRING in ...
