It's a known bug in GHC 4.08, fixed in GHC 4.08.1 which is about to
appear. It shows up when you mention a class in the type of one
of its own methods. Sorry about this!

| When I compile the following piece of code I obtain the very
| short message:
|
| AClass
|
|
| ----------------------------------
| \begin{code}
|
| module Main(main) where
| import Char
|
| class Point p where
| xBody :: Point self => (p -> self) -> p -> Int
|
| main :: IO ()
| main = putStrLn "Hola"
|
| \end{code}
|
| Notes:
|
| - That piece of code is taken from the translation used in
| the "Haskell++"
| paper
|
| - It seems to work ok in Hugs98 (I suppose that it also works in hbc,
| but I didn't try)
|
| - I am using ghc-4.08 in Debian linux and in Win32 (the same message)
