public class Test {
    public static Test t = new Test ();
    public static void main () {
        stdout.printf ("t is%s null\n", t==null ? "" : " not");
        var m = new Test ();
        stdout.printf ("t is%s null\n", t==null ? "" : " not");
    }
}

output:
t is null
t is not null

solution: the TYPE_TEST macro should be called before accessing a static ref. field.
Works fine if t is a value type like int.
