Comment (by simonpj):

 >  This sounds simple enough to be worth an explicit GHC proposal, but I'm
 happy to create one if you deem it's worth it.

 Yes, now I understand the proposal, thanks.  I do think it's worth a
 proposal.  I've been struck by how often people chime in with helpful
 comments that make the idea better. And it won't take long, and it
 documents the intent.  Plus, it's all about what users want, so asking
 users is a good plan.

 Why not add the empty case at the same time (only a user-manual change).

 Thanks!
