Description:
------------
in:
http://www.php.net/manual/en/language.namespaces.definition.php

It says: only four types of code are affected by namespaces: classes, interfaces, functions and constants.


It needs to be updated because TRAITS are also affected by NAMESPACES.


Test script:
---------------
namespace FOO;

trait fooFoo {}

namespace BAR;

class baz
{
    use fooFoo; // Fatal error: Trait 'BAR\fooFoo' not found in
}

Expected result:
----------------
only FIVE types of code are affected by namespaces: classes, interfaces, TRAITS functions and constants.
