Great, I'm okay with that.
But how do explain this?
http://docs.php.net/manual/en/language.namespaces.faq.php
namespace foo;
function bar() { }
bar(); // foo\ is prepended in compile-time
$x = 'bar'; // obviously foo\ will not be prepended
$x(); // hence 'bar' is not found

You mistyped 'world' on function call :-)
