For example QuickCheck is not required to build ghc, but if we included the Arbitrary instances for ByteString in the bytestring package then ghc would depend on QuickCheck.
Perhaps one solution is to use configurations, so people can build a package with or without the QuickCheck dependency.
What would a dependency on bytestring 0.9 mean then? How would I indicate that I need the Arbitrary instance? Someone could make a ghc-bootlib-arbitrary package, containing all the Arbitrary instances for types in the bootlibs. Thanks Ian
