"where not necessary" now becomes the problem. When is it necessary?

    ubyte n = 255;
    auto m = n + 2;

what type is m?

    uint x = 0xFFFFFFFF;
    auto y = x + 2;

what type is y?

These things obviously need clearly defined rules. Currently the rules
seem to be, if in doubt, use int. I don't know if that's necessarily
correct in all cases.
