Oh no, I love (most of) ES6 and enjoy it when something shows green on caniuse. But I dropped Babel/Webpack from my build and (personally) determined that not needing to deal with configuration, deprecation, etc. messages in my terminal was worth the +0.005s to initial render and using <script> tags in my index.html file.

That being said, I'll likely give this a spin tonight for somerandomcrappyidea.js and provide you guys some feedback. Unfortunately, my work at Google has me more focused on Angular so I don't have as much time as I'd like to work on React applications. =<

As an aside, thanks for the work you've done on Redux and the talk that you gave at Hack Reactor!
