Subject: declaring classes as static or final
From: michael.virnstein@brodos.de (Michael Virnstein)

Hi Devs,

what would probably be a nice addition:

1. static classes:
static classes can only contain static methods and attributes

<?php
static class foo {
	public static function bar() {}
}
?>

2. final classes:
final classes can't be extended

final class foo {
	public function bar() {}
}

3. final static classes
final static classes can only contain static methods and attributes and 
can't be extended.

final static class foo {
	public static function bar() {}
}

What do you think about it?
