No, it doesn't mean that (I was talking about methods that don't really
have object contexts). Frankly, I'm not really sure what you're after.
You can pass that function a 'pointer' to an object, and a method name, and
call $object->$method(). I think you could do that in PHP 3.0, but if you
couldn't, you can do it using PHP 4.0.
