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.
