199,failure to parse strict field in GADT style type declaration,ganesh,nibro,"This file parses fine in ghc:
{{{
{-# LANGUAGE GADTs #-}
module Foo where

data X where
  X :: !Int -> X
}}}
HSE (e.g. via hlint) fails to parse it with:
{{{
Foo.hs:5:8: Parse error
Error message:
  Parse error: !
Code:
    data X where
  >   X :: !Int -> X
}}}

This is with version 1.9.4 but that's not an available version.
