I have exactly the same feelings as Reinhard on this. If you want to pass something to child
use request parameters for simple values or POST request (using postable source) for passing
complicated structures. The same goes for passing data from sub-request to parent one.

Basic goal behind such design is to really, really avoid any possibility of side-effects.

Nevertheless, I'm also eager to hear others' opinions.
