| Subject: [Haskell] deriving with newtypes
| 
| Hello,
| 
| I'm trying to use GHC's deriving mechanism for newtypes in the
following way:
|     class C a b
|     instance C [a] Char
|     newtype T = T Char deriving C [a]
| Unfortunately, this isn't possible. Is there a reason for this? Can I
| circumvent this restriction?
|
