Woohoo!

In that case, unless downstream packagers say otherwise,
I'd say go with transformers 0.3 if we can do it at our end
without pain. I think any actively maintained package will
soon move to 0.3; it's easy to do, usually just a cabal
version bump for a minimal upgrade, and there are clear
advantages in performance and API. From the chicken and
egg perspective, maintainers outside the platform will be
encouraged to upgrade promptly if the platform does it.
