Description

This is a place holder ticket for people that try to use DPH and find problems or missing features. DPH is still deeply experimental, and we don't expect you to be able to do anything useful with it yet.

However, it may work well enough to compile and run programs, depending on your particular example. The compiled executables are likely to work, but they will be very slow (like 10 - 100x slower than they should be). If you'd like to try DPH out anyway then feel free to give it a shot. Further questions and comments should be directed to benl@…. No need to open a ticket here in the GHC trac.

(In #7091) The paper claims *work* efficient vectorisation, not *space* efficient vectorisation. Making it space efficient is an open research question.
