-// QHashField can be used for doing coarse grained set testing, in
-// cases where you do not expect the set to contain the item.  For
-// example where you would write:
-//     QSet<QString> strings;
-//     for (int ii = 0; ii < mystrings.count(); ++ii) {
-//         if (strings.contains(mystrings.at(ii)))
-//             qFatal("Duplication!");
-//         strings.insert(mystrings);
-//     }
-// You may write:
-//     QHashField strings;
-//     for (int ii = 0; ii < mystrings.count(); ++ii) {
-//         if (strings.testAndSet(qHash(mystrings.at(ii)))) {
-//             // The string *might* be duplicated
-//             for (int jj = 0; jj < ii; ++jj) {
-//                 if (mystrings.at(ii) == mystrings.at(jj))
-//                     qFatal("Duplication!");
-//             }
-//          }
-//     }
-// For small lists of things, where the hash is cheap to calculate
-// and you don't expect duplication this will be much faster.
