I think this is on
using GroupedItems = hash_map<string_view, std::vector<string_view>, XXHasher>;
static void printItemMap(const GroupedItems& itemMap)
{
 auto printSet = to_vector(view::transform(itemMap, [](auto& p) {
  return strCat(formatSet(p.second, 15), ' ',
                formatHelpText(p.first, 50, 20));
 }));
 ranges::sort(printSet);
 for (const auto& s : printSet) {
  cout << s << '\n';
 }
}
