Bug description:request for interface hashCode (Identifiable)

Description:
------------
i, i hope to see something like this in future php releases





interface Identifiable

{

     public function /*string*/ hashCode();

}





class Test implements Identifiable

{

     public function hashCode(){return spl_object_hash($this);}

}





method hashCode() should be called in these contexts:





$myarr[new Test()] = "test";

$myarrobj->{new Test()} = "test";

and manually inside:

function method(Identifiable $instance){};





the hash should be obtained by calling



$obj->hashCode()     if it is Identifiable or

$obj->scalarValue()  if it implements ScalarAccess

$obj->__toString()   if it has method __toString



or, finally throw an error



what do you think about this?

thank you
