Though I'd love to see pure/return unified, I almost wonder if it'd be
a good idea to wait a bit on this. By which I mean, rather than having
a bunch of little breaking changes as we try to fix things piecemeal,
perhaps it'd be better to fold this proposal (and similar ones) into
the next Haskell' report (assuming we can actually ship it this time).
That way we can just have a big break-the-world change in the
transition to Haskell2020 (or whatever).
Not sure if that's the best approach, especially given the difficulty
in getting Haskell2020 finalized, but it might be worth thinking
