No, you're right there is nothing mysterious... 
The problem here is indeed to keep control over the horizontal position
and current value of the indentation to generate the line breaks while
running through the tree.
Updatable variables are eagerly missing here and I don't see how you can
easily perform this task which would be trivial with any procedural
language.
Have I missed something ?

Thanks
