void main() {
    uint a;
    float b = 0.1;
    a += b;
}

This program compiles no problem. This is obviously a problem and a very surprising behavior; I'm at the end of a 2-hours bug chasing and tried this only after I eliminated all other opportunities for error.

For numeric types, It is ok for built-in += to perform narrowing conversion, but not truncating ones.
