can implement it on the inside with ```cs public static class PtrAccessor { public static PtrT

public static class PtrAccessor  
{
    public static PtrType<T2> Get<T2, T>(this PtrType<T> self, int i)
        where T: IPtrMarker<T2>
    {
         // IDK take an index and do magic with the inner of PtrType
        throw null;
    }
    public static PtrType<T3> Get<T3, T2, T>(this PtrType<T> self, int i, int j)
        where T: IPtrMarker<T2>
        where T2: IPtrMarker<T3>
    {
        return self.Get(i).Get(j);
    }
}

public static class PtrAccessor  
{
    public static PtrType<T2> Get<T2, T>(this PtrType<T> self, int i)
        where T: IPtrMarker<T2>
    {
         // IDK take an index and do magic with the inner of PtrType
        throw null;
    }
    public static PtrType<T3> Get<T3, T2, T>(this PtrType<T> self, int i, int j)
        where T: IPtrMarker<T2>
        where T2: IPtrMarker<T3>
    {
        return self.Get(i).Get(j);
    }
}
