 Replying to [comment:14 thomie]:
 > What is the difference between `import qualified A` and `import A
 qualified` (row 3)?

 You're right. Those are the same. I've edited it all to clarify.

 `import qualified A (..)` brings `A.x` and `A.y` into scope.

 `import A (..) qualified` brings `x`, `y`, `A.x`, and `A.y` into scope.
