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:
class myCountable implements Countable
  function count()
    return 0;

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

Expected result:

Actual result:

Even with count() returning null an object often is a "true" value and we decided not to add other casting functions (other than __toString())
