If VRP is unknown then it should be disallowed for precisely
that reason! It can't implicitly cast back to a byte, so it

cast yourself, that's what it's for.
Question though, how do you physically write the cast for:
byte a;
a += 1;
With a + 1, you can cast that whole right hand side. But with
+=1, there's nowhere to put the cast! If you cast(byte) 1, it
changes nothing, since it could still overflow.
