New description:

 Unqualified exports of constructors doesn't work anymore in 8.2.1-rc1. It
 worked before in 8.0. Is this intended or a regression?

 {{{#!hs
 module Test (
   GHC.Exts.IsList(
       Item
       , fromList
       , toList
       )
   , Data.Bool.Bool(True, False)
 ) where

 import qualified GHC.Exts
 import qualified Data.Bool
 }}}

 The error:


 {{{
     • Not in scope: data constructor ‘False’
       Perhaps you meant ‘Prelude.False’ (imported from Prelude)
     • In the export: Data.Bool.Bool(False, True)
 }}}
