unhelpful error message about enabling TypeApplications
% cat bug.hs
{-# LANGUAGE TypeApplications #-}
main = return (id@() ())
% ghc bug.hs
[1 of 1] Compiling Main ( bug.hs, bug.o )
bug.hs:2:16: error:

Did you mean to enable TypeApplications?
This error message makes no sense because TypeApplications
is already enabled.
