Constrained method type accepted in Haskell 98 mode
If I understand this paragraph of the GHC manual correctly, the following code should be rejected in Haskell 98 mode:
{-# LANGUAGE Haskell98 #-}
module Main where
class Compare a where
comp :: Eq a => a -> a -> Bool
However, it compiles fine for me both with 7.4.2 and 7.6.1.
