I don't think we > have here something like the templates in time, really. But if we round first modulo 2^64 then modulo m, it isn't the linear congruential algorithm it is supposed to be. I think I'd prefer for the compiler to reject the code when used with values that would make the generator too slow. Let me ask on the reflector, to be sure.
