use function and use const

The use operator has been extended to support importing functions and constants in addition to classes. 

<?php
namespace Name\Space {
    const FOO = 42;
    function f() { echo __FUNCTION__."\n"; }
}

namespace {
    use const Name\Space\FOO;
    use function Name\Space\f;

    echo FOO."\n";
    f();
}
?>
