Thanks, so the `return scope` means «allow escape», not 
necessarily return?

But that only works for this very special case. It falls apart 
when you try to add a third node. As far as I understand, 
`scope` cannot handle linked lists. A `scope` pointer cannot 
point to another `scope` pointer.

One can do two levels, but not three. Got it. Works for some 
basic data-structures.
