Sorry if it has been discussed before, but how is the
question about __clone accept arguments ???
It would permit a better control when clonning
objects, like dinamically setting properties.

Sure its is possible using wrappers, but would be
better if the function supports that.

class clonable{

        public $age;
        public $b;

//      function __clone($a){
//              if ($a) $this->age = $a;
//              else $this->age = $that->age;
//      }

}

$molly = new clonable;

$molly->age = 1;

$dolly = $molly->__clone(0);

echo $dolly->age;

if ($dolly == $molly) echo "equal: TRUE";
else {
        var_dump($dolly);
        var_dump($molly);
}
if ($dolly === $molly) echo "identical: TRUE";
else {
        var_dump($dolly);
        var_dump($molly);
}

It doesn't accept arguments. An object should know how to clone itself 
without additional information. If you want a method which does something 
other than cloning then define your own method.
