You can use a proxy object, something like this:

#include 

struct Object
{
    struct Proxy
    {
        Object *mObj;
        int mI;

        Proxy(Object *obj, int i)
        : mObj(obj), mI(i)
        {
        }

        int operator[](int j)
        {
            return mI * j;
        }
    };

    Proxy operator[](int i)
    {
        return Proxy(this, i);
    }
};

int main()
{
    Object o;
    std::cout << o[2][3] << std::endl;
}
