Description:
------------
Referring to the English manual page about "Using namespaces:
Aliasing/Importing"
http://php.net/manual/en/language.namespaces.importing.php

Example #5 is supposed to show an illegal importing rule. What it
actually shows is something different: the insertion of a Trait.
This is (now) perfectly valid PHP, it just does something different
from what the page is describing.

I assume the example was added before we had traits; it should be
updated to avoid confusion. Since the preceding paragraph is
referring to scope, perhaps the class should be replaced by a
function.

Test script:
---------------
<?php
// not a test script, this is example #5 from the manual page

namespace Languages;

class Greenlandic
{
    use Languages\Danish;

    ...
}
?>
