If an immutable int x is inside the if branch that asserts it to be not
negative, the assignments and comparisons with an uint should not give
warnings:


uint z;
void main(string[] args) {
    immutable int x = args.length - 3;
    if (x >= 0) {
        uint y = x; // give no errors here
        if (x > z) {} // give no warning here.
    }
}
