We will accidentally have the correct behavior when the user selects a set of fields starting with the first field and not skipping any fields in that range. So for a struct with fields `a, b, c, d`, we will have correct behavior for reading `a` or `a, b` or `a, b, c`, or `a, b, c, d`. -- This is an automated message from the Apache Git Service.
