-Haskell Compiler Plugin which removes unused imports automatically.
+> “So many people consider their work a daily punishment. Whereas I love my work
+> as a translator. Translation is a journey over a sea from one shore to the
+> other. Sometimes I think of myself as a smuggler: I cross the frontier of
+> language with my booty of words, ideas, images, and metaphors.”
+>
