Consider this:

        byte a = 6, b = 7;
        auto c = a + b;

        writefln("%s, %s", typeof(c).stringof, c);
        writefln("%s, %s", typeof(d).stringof, d);
}

Output :
int, 13
int, 0

I really wish d gets promoted to a float. Besides C compatibility, any reason why d got promoted only to int even at the risk of serious bugs and loss of precision?

I know I could have typed "auto a = 6.0" instead, but still it feels like an half-baked promotion rules.

Integer division and modulo are not bugs.
