Very interesting write-up. Definitely cuts down on the boilerplate.

Would be good to explain what `react-redux-provide` does under the hood. It might help convince redux users that the package is doing some of the work for them.

Also what would the code look like without the @provide decorator? [Stick to ES6, it's already crazy enough, no need to jump to ES7 stuff]

I believe most of what it's doing under the hood is explained in the article. Sorry if it isn't 100% clear.

Short version:

- A provider has its own store (or it can share a store with other providers if you need it to).

- When you have a `propType` matching a provider's `actions`, those actions are automatically mapped to the store's dispatcher; so when you call `this.props.someAction`, it's essentially calling `provider.store.dispatch(provider.actions.someAction())`.

- And when you have a `propType` matching a provider's `reducers`, that component will always have the latest state of that reducer.

Without the `@provide` decorator, you would just `export default provide(SomeComponent)`. I've opted to use the ES7 decorator because it's cleaner, more concise, and immediately apparent.

It was already pretty clear, but your point-form explanation makes it even more clear. Somehow, I imagined there was more "magic" going on behind the scenes, but it's actually just matching this.props with actions and reducers.

This is a really neat idea, though I can imagine there might be some problems name conflicts for larger applications... still, it totally looks like something I will play with in the comping weeks. Thx for the writup and the above concise explanation.
