Module, that exports another ones

Question

Is there a way to create a module that will export other modules?

For example, I have a list of modules: A, B, C. And I want them to be imported to module D.

So, I have to write:

import A
import B
import C

It works. But may be not very convenient sometimes.

Is there a way to create a Collection module that exports the content of A, B and C?

With this feature, instead of previous instructions, I'd only have to write:

import Collection -- Importing A, B, C.

Answer 1

Yes, but you need to use an explicit export list, specifying all functions, types, classes and modules to export from this module.

module Foo (module A, module B, myid) where

import A
import B

myid :: a -> a  -- For example
