Comment:

 The export list syntax itself stays unmodified and I adjusted the example
 'That (annoyingly) means that you cannot selectively import Y selectively,
 thus "import Y( D(D1,D2) )", because Y does not export D.' already. See
 the `docs/users_guide/glasgow_exts.rst` diff in Phab.

 I'll edit the comment. I was trying to phrase what I was doing in a
 general way but I got a bit too general.
