use Spiffy\Dispatch\Dispatcher;

$d = new Dispatcher();

// assume the TestDispatchable class from above
// instead of this
$d->add('foo', new TestDispatchable());

// you would do this
$d->add('foo', function() {
    return new TestDispatchable();
});

// the output is identical to the output from Dispatchable above
// the only difference is that it's lazy loaded on dispatch() instead.
