Hm,

no instance Arbitrary Char is provided in the QuickCheck modules that came with my hugs or ghc. Probably the author just forgot to import Data.Char. Try inserting that in QuickCheck.hs.

Hope that works, Daniel

Hugs used to (non-standardly) import some functions from the Char module. A bit back on the #haskell channel someone mentioned a similar issue, they also had issues with fromInt which should likely be replaced with fromIntegral. Presumably the Hugs QuickCheck accidently relied on these non-standard aspects.
