Subject: getInstance and new self()
From: jeff@opendbms.com ("Jeffrey Moss")

I found this on a zend engine 2 list archive, but didn't see an answer, has
it been resolved? I am trying to create a singleton class heirarchy without
having to override getInstance....

<?php
  class Test {
    public static function getInstance() {
      return new self();
    }
  }

  class Foo extends Test {
  }

  var_dump(Foo::getInstance());
?>
thekid@friebes:~/devel/php/tests > php5 self.php
object(test)#1 (0) {
}

Expected output would be "object(foo)", so I guess either "self" should
not be evaluated at compile time or this should be disallowed. I'd
prefer the first:)
