Hi,

I just stumbled over the createObject function which has a massive switch to decide how an object should be created, depending on the amount of arguments.

    switch (count($args)) {
        case 1:
            return new $type($args[0]);
        case 2:
            return new $type($args[0], $args[1]);
        case 3:
            return new $type($args[0], $args[1], $args[2]);
        case 4:
            return new $type($args[0], $args[1], $args[2], $args[3]);
        case 5:
            return new $type($args[0], $args[1], $args[2], $args[3], $args[4]);
        case 6:
            return new $type($args[0], $args[1], $args[2], $args[3], $args[4], $args[5]);
        case 7:
            return new $type($args[0], $args[1], $args[2], $args[3], $args[4], $args[5], $args[6]);
        case 8:
            return new $type($args[0], $args[1], $args[2], $args[3], $args[4], $args[5], $args[6], $args[7]);
        case 9:
            return new $type(
                $args[0], $args[1], $args[2], $args[3], $args[4], $args[5], $args[6], $args[7], $args[8]
            );
        case 10:
            return new $type(
                $args[0], $args[1], $args[2], $args[3], $args[4], $args[5], $args[6], $args[7], $args[8], $args[9]
            );
        case 11:
            return new $type(
                $args[0],
                $args[1],
                $args[2],

                $args[7],
                $args[8],
                $args[9],
                $args[10]
            );
        case 12:
            return new $type(
                $args[0],
                $args[1],
                $args[2],

                $args[11]
            );
        case 13:
            return new $type(
                $args[0],

                $args[3],
                $args[4],
                $args[5],
                $args[6],
                $args[7],
                $args[8],

                $args[7],
                $args[8],
                $args[9],
                $args[10],
                $args[11],
                $args[12],
                $args[13]
            );
        case 15:
            return new $type(
                $args[0],
                $args[1],

        default:
            $reflection = new \ReflectionClass($type);
            return $reflection->newInstanceArgs($args);
    }

So PHP 5.6 added a new operator, also named the splat operator in other languages to unpack arguments, so whenever you decide to change the min. version to 5.6 this massive switch could be replaced by this simple line:

return new $type(...$args);
