I believe that all you'd need to do is make it so that arr[1] returns an 
object which you can do the [3] on and get what you want. If returning an 
array works for that, then there you go. If you need another struct, then 
define the other struct. However, I would point out that you'd need a third 
template argument to Array for the type (unless you want it to hold a 
Variant).
