When deriving Data with all warnings enabled, for example compiling the
following line:
data TestType = TestType Int deriving (Typeable,Data)
ghc 6.2 gives the following warnings:
Warning: Pattern match(es) are non-exhaustive
In a case alternative:
Patterns not matched: GHC.Base.I# #x with #x `notElem` [1#]
Is there a problem with the 'derived' code, or should this warning be
ignored?
regards,
Keean Schupke.
