Subject: __invoke() weirdness
From: david.zuelke@bitextender.com (=?ISO-8859-1?Q?David_Z=FClke?=)

Hi folks,

I played with __invoke today:

class Curry
{
   protected $callable;
   protected $args;

   public static function create($callable)
   {
     $curry = new self($callable, array_slice(func_get_args(), 1));
     return $curry;
   }

   protected function __construct($callable, $args)
   {
     $this->callable = $callable;
     $this->args = $args;
   }

   public function __invoke()
   {
     return call_user_func_array($this->callable, array_merge($this- 
 >args, func_get_args()));
   }
}

However, it doesn't work consistently.

This works fine:
   $d = new DateTime();
   $getAtom = Curry::create(array($d, 'format'), DATE_ATOM);
   echo $getAtom();

This gives a fatal "Call to undefined method DateTime::getAtom()"
   $d = new DateTime();
   $d->getAtom = Curry::create(array($d, 'format'), DATE_ATOM);
   echo $d->getAtom();

Is that intentional?

Cheers,

David
