This reverts commit 033681af8941d9678961f985c13e500c3c70f337, reversing
changes made to a2d66c0fc8ee58e82be3efd59173803e66dee3e0.
I brought you into this world, and I can take you out.
I'm extremely stupid and didn't commit as I go. To anyone reading this
I'm extremely sorry. A lot of these changes are very broad and I plan on
releasing Babel 6.0.0 today live on stage at Ember Camp London so I'm
afraid I couldn't wait. If you're ever in London I'll buy you a beer
(or assorted beverage!) to make up for it, also I'll kiss your feet and
give you a back massage, maybe.
