Comment (by j.waldmann):

 What do think is the error here?

  An individual language pragma begins with the keyword LANGUAGE and is
 followed by a comma-separated list of named language features

 https://www.haskell.org/onlinereport/haskell2010/haskellch12.html#x19-19100012.3

 This list can be empty (it does not say otherwise), so `{-# LANGUAGE #-}`
 is fine.
