Define class with slot with @SlotFor annotation

namespace Maslosoft\Ilmatar\Modules;

class MyModule
	 * @SlotFor(MyNamespace\Signals\AccountMenuItems)
	public function reactOnAccountMenu(MyNamespace\Signals\AccountMenuItems $signal)

$signal = new Maslosoft\Signals\Signal();
$result = $signal->emit(new AdminMenuItems());

echo $result[0]->item[0]['label']; // My blog
