It goes on like this for all of chapter 21 and 22.

I want to write a a template haskell function deriving show for data types
without constructor.
-- example
-- data A a
-- the derived instance:
-- instance (Show a) = Show (A a) where
-- show _ = A ++ show (undefined :: a)
deriveShowNoConstructors :: Name - Q [ Dec ]
N.B. if you want a faster answer such questions are best posted to

My answer: I asume that your function all_rotations somehow needs to be
called recursively for the rest of the input list xs.
Cheers Christian

Hi all,
There exist a really neat solution to this. I think that it is pioneered
by Doaitse Swierstra and Luc Duponcheel in their parser combinators:

What you need to do is write a function that operates on a string that does
what you want it to, and then use that to write some top-level I/O code.
If you have a function sortFile :: String - String, you would write
something like this for main:
main :: IO ()
main = do
string -
