 In the following

 {{{#!hs
 data FieldOcc pass = FieldOcc { extFieldOcc     :: XFieldOcc pass
                               , rdrNameFieldOcc :: Located RdrName
                                  -- ^ See Note [Located RdrNames] in
 HsExpr
                               }

   | XFieldOcc
       (XXFieldOcc pass)
 }}}

 we are using `XFieldOcc` for both the `extFieldOcc` type and the extra
 constructor.

 The first one should be `XCFieldOcc`/
