It's not worth upgrading these to support QuickCheck 2.8, as I no longer use these packages. I have removed the dependencies on these packages from my packages; no other Stackage packages depended on them. These packages were intended to solve two evils that often arise during testing (orphan instances and Template Haskell); however, I have reluctantly concluded that those evils are the lesser of other evils so these packages are no longer needed.
