you're using). But, on Win32 platforms, many compilers use a
calling convention which is identical to the 'stdcall' calling convention,
so attributing your 'foreign import' declarations with stdcall
should get you there. At

instance Random Int
in GHC's library pre-dates the existence of the genRange class
operation for RandomGen. GHC's implementation of the instance
behaves extremely badly when given a random generator with
only two values (as in your example).
I would love

instance Bounded Char where
minBound= '\0'
maxBound= '\x'
I didn't follow all the discussion about unicode, but the maxBound seems
to be wrong. It probably should be '\x10'. The exact specification
could also be avoided by

data T deriving (Show) -- or Eq, Ord, ...
personally I think this should be legal. the actual semantics are
irrelevant, as far as I can tell, since you won't ever have something of
type T other than _|_ and so you could simply
