Thanks Bertran for your solution. I have difficulty understanding it so I
can't comment on it right now but I'll try to have a look at it. Do you
know of any article that explains this technique, starting from very
simple examples?

I should add that this possibility was the main reason for dealing with
blueprints at all. As Ross Paterson's solution shows, it's possible to
get simpler code without balancing the tree.
