Description Aaron Andersen 2010-06-16 14:14:52 UTC 
public struct Vector3 {
    public float x;
    public float y;
    public float z;
}

public class Foo {
    public Vector3 position {
        get;
        set;
    }

    public Foo () {
    }
}

int main (string[] args) {
    var f = new Foo ();

    // both of these compile fine in vala, 
    // but generate c code which will not compile
    f.position.x++;
    f.position.x = 10.0f;

    return 0;
}
Comment 1 Jürg Billeter 2010-10-16 10:57:25 UTC 
This is invalid code, Vala should not allow modifications of temporary struct values. The test case actually compiles now, however, it modifies temporary variables which is probably not what you intended.
