[Haskell-cafe] Quick Question for QuickCheck2

perhaps I am just blind or is it a difficult issue: I would like to
generate Char values in a given Range for QuickCheck2. There is this
simple example from the haskell book:
instance Arbitrary Char where
arbitrary = elements (['A'..'Z'] ++ ['a' .. 'z'] ++ " ~!@#$%^&*()")
This does not work in QuickCheck2 since the instance is already
defined. How do I achieve this behaviour in QC2?
Thanks for helping.
