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 ...

In the end of http://docs.php.net/manual/en/migration53.incompatible.php page are mentioned the new keywords introduced in 5.3.
But yes, the FAQ. needs an update to state this point.

Thanks.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

quoting the migration guide:

"The following keywords are now reserved and may not be used in function, class, etc. names.

    * goto
    * namespace"
