My only question when reading on the CB what what happens with duplicate keys. Perhaps a non-default mechanism to allow for it to emit an HoAoH. LA's case assumes (or ensures, take your pick) no duplicates, so it is a non-issue for her. Update: Quite right Tux. I skipped over the map line and took it as what was returned.

My only other issue would be with the name. csv2list implies that it is returning a list. It is returning a hash (well, hashref), not a list.
