A little more clarification,  following interface definition is allowed or
not?

interface Some {

  require($this->last_result > 1000); // Force classes to have $this->result

  function bar($a, $b)
     require($a > $b)
     return($ret, $ret > 1000);

  function getLastResult()
     return($ret, $this->last_result === $ret);

}

I suppose it is supported, but it may be better to be explicit.

Regards,
