I think the current syntax may be clearer:

<?php
namespace blah;
include 'file/with/foo/namespace.php';
use foo/something;
$f = function() use ($x) {}
?>

<?php
namespace blah;
include 'file/with/foo/namespace.php';
use foo/something;
$f = function()
{
use $x;
}
?>

The second version requires a visual re-parsing, the first is clear at a
glance.  In addition, if support for namespaced variables was ever
introduced, confusion would abound.

Thanks,
Greg

P.S. happy new year (I'm a bit slow)
