To provide the exact available signatures, to let user quickly find what is his mistake @comphead But we will also handle this while checking signature of array. Why do we need to check it here again? Is there any usage that skip the signature checking but jump to this call directly? If yes, we need to find a way to reuse the checking because the coercion is not supported here currently, length checking may not be enough. -- This is an automated message from the Apache Git Service.
