Added test for nested property

[laptobbe]

Can't figure out how and what to change to make it work thought. Do you think this is a good idea to support? or I am I doing it wrong?

You want to add some error treatment?

No I would like for it to work like the test shows. So that you can extract a value deeper into the structure to the current level. If that makes sense :P
