[QuickCheck] 2.7 is a huge pain in the ass

Hi Bryan,

Sorry to hear this. I do try hard to avoid making breaking changes to
QuickCheck, but as there hadn't been a significant QuickCheck release
for nearly two years (my fault) there were a couple of API changes
this time. Can I ask what exactly you ran into?

I also have a mirror of Hackage that I grep to assess the impact of
any API change, and back out if it's too severe, but this time I
must've missed something. I think in the future I will also build HP
with the new version to stop this happening again.

Nick
