Originally, this was seen as a way to handle + cases where we had columns returned with difficult-to-predict names, + though in modern use that issue has been overcome by anonymous + labeling. In this version, the approach basically reduces function + call count per-result by a few dozen calls, or more for larger + sets of result columns.
