New Comment:
$a->intVar = 12 is overwriting the old intVar property, keeping the old
value would be a major beak to the way PHP works.

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.
