Why not use a std::map ? You can easily achieve what you want by using a map. All you have to do is implement a comparison (> or < ) operator.

If you insist on using a std::list, you will have to iterate through the list, and check whether the element at each position matches yours. You'll have to come up with a way to check if two of your objects are equal.
