Your solution is beautiful and a great demonstration of Boost Coroutine. 

For what it's worth, I had also used an earlier incarnation of Boost
Coroutine (while it was being reviewed) as a stackful coroutine
implementation, but wasn't so clever in the use of visitors and
reimplemented/copied the algorithm with added yield statements. That
solution was very inefficient and I discarded it. 

Boost Coroutine has changed (and surely improved) a lot since then. I would
be curious to know the computational cost of the inversion of control using
your method. Have you tried to quantify it?
