Jeroen Weijers reports: I have two files `Data.hs` and `Class.hs` (`Class`
depends on `Data`). When I compile `Class.hs` (`ghc --make Class.hs`) the
ghc does what it should do.
When I now make a change to `Class.hs` (add a newline to the end of the
file for example) and try to run `ghc --make Class.hs` again the ghc gets
stuck on recompiling `Class.hs`.
{{{
module Class where
import Data
foo :: Exp a
foo = error "urk"
{-# LANGUAGE GADTs #-}
module Data where
data Exp a where
LamE :: (Exp a -> Exp b) -> Exp (Exp a -> Exp b)
}}}
