Function overwriting

Is it possible(maybe in php future) that when you extend a class that you can disable function overwriting or does it apply to the final class php5 uses?

Code:

class x
{
   final function base()
   {
       echo 'main';
   }
}
class y extends x
{
   function base()
   {
       echo 'main2';
   }
}

will it error out or is it possible to stop the error and allow access to the root class without overwriting that function.

Code:

$cls = new y();
$cls->base();//would this output main?

If the function in the parent didn't have the final keyword attached to it then it would echo out main2. However, as you've applied the final keyword, then a fatal PHP error will be evoked.
