Yo, Marco :P I don't need to add any contextual data, I'm just trying
improve consistency by formalizing what PHP already does. I think it's the
right way to fix this because I don't think changing PDO is ever going to
happen. You either special case PDO in your code or formalize the special
case so that it becomes the norm. Again, there is no actual formal type
restriction right now, existing code that assumes `int` is wrong, even if
it's not their fault. If you are making that assumption your code is broken
already.
