I doubt you're stupid; a stupid person wouldn't know what GROUPING SETS meant,
wouldn't bother finding out, and certainly wouldn't bother trying to implement
it. It's very helpful that you've let us know you're not working on it. That
way Pavel, if he finds he has time and interest, or someone else, can work on
it without fear of conflicting with what you're doing. Thanks for your work;
please don't get discouraged!
