Non-ideal error message for misplaced LANGUAGE pragma
Placing the LANGUAGE pragma anywhere besides the top results in it not being accepted - thus this should result in an error message.
Trivially:
import Data.Maybe
{-# LANGUAGE EmptyDataDecls #-}
data AThis would be minorly more annoying for TypeFamilies, who's error doesn't mention language extentions: "Data/Queue.hs:30:0: parse error (possibly incorrect indentation)"
