This project is about pushing the practical use of the parallel
techniques that are already mature, rather than about pushing research
projects along further.
So this project is not really about DPH. On the other hand it's possible
someone might be able to make more immediate use of the dense, regular
parallel arrays which has been a recent spinoff of the DPH project. They
have the advantage of being considerably easier to implement, but much
less expressive than the full sparse, nested parallel arrays.
