Description 

% 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:
    Pattern syntax in expression context: id@()
    Did you mean to enable TypeApplications?

This error message makes no sense because TypeApplications is already enabled.
