Bug description:  New magic method __setValue for REAL type checking.

Description:
------------
It's a feature request for a new magic method named __setValue (could be
other more suitable name)

There is already magic method named __set, which is called when
inaccessible MEMBER is called. The one I propose should be called when
Object is called, receive the value that this object is being set to, and
return new value. For example:

class Int32 {
 function __setValue($value) {
   if (!is_int($value)) throw new Exception("Type checking...");
   return $value;
 }
}
class A {
 public $intVar;
 public function __construct() {
  $this->intVar = new Int32();
 }
}
$a = new A();
$a->intVar = 12; //is ok
$a->intVar = "asdf"; //throws exception

That feature would give TONES of new possibilities, type checking is one
of them.
