From:             
Operating system: Any
PHP version:      5.3.2
Package:          SPL related
Bug Type:         Feature/Change Request
Bug description:Controlled typecasting for objects that implement the "Countable"
interface

Description:
------------
Now we have no ways to controll type casting of Countable-objects to
boolean 
type. We would like to work with the SPL-derivatives, as well as with the
built-
in types.

Test script:
---------------
<?php
class myCountable implements Countable
{
  function count()
  {
    return 0;
  }
}

var_dump((boolean) array());
var_dump((boolean) new myCountable());


Expected result:
----------------
bool(false)
bool(false)


Actual result:
--------------
bool(false)
bool(true)
