What this does is:

1. try to create a link between url ”/v” and ”/p” using relative url syntax
2. create a Value node at url ”/v”
3. create a Print node at url ”/p”. This operation creates the pending link v => p.
4. set “value” of “v” to 7
5. get “value” of node “v”
6. unlink “v” and “p”
7. get “value” method again
8. quit
