I'd be in favour of that. This would also make it possible to either add unordered-containers to the platform, or (preferably) merge unordered-containers into containers.

I want to do the latter. Now when the implementation of unordered-containers is stable it makes sense to integration it into containers and expand the API. I think Hashable might have to go into base. It's hard to have core type classes outside of base due to orphan instance problems. -- Johan
