just my attitude, but I think lack of ordering or grouping support is right up there with lack of transitive closure logic as a most unfortunate omission. maybe that goes back to the times when I couldn't understand why either the biggest number or the smallest number wasn't printed first on the 1403 fan-fold pages, preferably the largest absolute number first AFAIWC. my attitude is probably completely psychological and maybe pathological too as far as some are concerned. can't give conventional, aka current, justification for that, sorry!
