Notes

Wenn die eingebaute operator< liefert keine totale Ordnung für Zeiger, wird eine partielle Spezialisierung std::less für Zeigertypen vorgesehen, die garantiert totale Ordnung .

Original:

If the built-in operator< does not provide total order for pointers, a partial specialization of std::less for pointer types is provided, which guarantees total order.
