As far as I’m aware there is not currently a way to do this.
What I usually end up doing is having a central module that re-exports important things as a convenient way to import everything that is necessary while not hiding anything in the modules defining these things (which in some cases – that you probably won’t foresee! – makes it easier for your users to modify things in your module).
To do this use the following syntax:
-- |Convenient import module
module Foo.Import (module All) where
-- Import what you want to export
import Foo.Stuff as All hiding (local_func)
-- You can import several modules into the same namespace for this trick!
-- For example if using your module also requires 'decode' from "Data.Aeson" you can do
import Data.Aeson as All (decode)
You have now conveniently exported these things.
