--- Comment #10 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-01-27 13:01:23 UTC --- Really, I don't think the intent here is involving arbitrary size integers. This stuff must be quick, and all the integers are unsigned. I don't think we have here something like the templates in time, really.
