Let me guess. You are coming from Java. In Java this would be: myArray.sort(new Comparator<MyClass> ({ @Override CompareTo(MyClass lhs, MyClass rhs) { return rhs.compare(lhs); } })); Is that really shorter? I don't think so. In any case, there is a more elegant solution in Go, which is simply: sort.Sort(sort.Reverse(array)) You need to open your mind a little bit, to learn a new language.
