I think there should be a ghc-7.6 branch for DPH.

I think Ian should branch DPH along with the other libraries as part of the 
release process. From then on I'll test it with the current GHC version and 
ship it via Hackage as I've been doing. Ian doesn't have to wait for me once 
the branch has been made.

I expect Ian didn't branch DPH because it's not his job to test it with the GHC 
RC and ship it as part of the GHC source tarball. I can do the release part, 
but if Ian branches DPH as well then it is effectively zero-overhead to his 
existing workflow, and we won't hit this breakage again (I think?).

Ian: let us know if you have a better idea for it.

Ben.
