What potential issue could arise from using "$this->Smarty();" in the code?

Using "$this->Smarty();" in the code could potentially cause an error because it is not the correct way to instantiate an object of the Smarty class. Instead, you should use "$this->smarty = new Smarty();" to properly create an instance of the Smarty class and assign it to the property "smarty" of the current object. 

class Example {
    private $smarty;

    public function __construct() {
        $this->smarty = new Smarty();
    }
}
