Hi Max.

Thanks a lot for this example!

Cloning it's just one of the things that I had in mind :)

If I remember correctly right from the very first days of V4 announcement these were the "cornerstones" we ever agreed on :
1) 64Bit
2) Instancing
3) Grouping

I'm confident that during the V4 beta period Michael will give us 2 and 3 also :)

Ciao!
