Thank you for the PR!
I don’t know TypeScript so leaving this for @aikoven and @ulfryk to review.
(It should indeed be optional, and we should support omitting both preloadedState and enhancer.)

Isn't the case of omitted preloadedState already covered by the first overload of StoreCreator?

I learned Typescript four days ago, so bear with me :).

I needed to create a store with redux-socket.io middleware. The key line is here:

const store = applyMiddleware(socketIoMiddleware)(createStore)(reducer)

The typescript compiler was erroring out (no matching type definition for call target) until I added the peloadedState argument:

const store = applyMiddleware(socketIoMiddleware)(createStore)(reducer, {})

I thought I tracked the type definition down to the right place, but it is quite possible that I am off a bit. I am pretty new at this.

Let me know if there is something else I can do to verify the change that needs to be made here without it being too much work for you.

I am using Redux v3.5.2 and Typescript v1.8.10.

@raineorshine You are right, your change to StoreEnhancerStoreCreator fixes exactly your issue.

But change to StoreCreator is unnecessary and creates a bit of ambiguity for which overload to use when calling it with exactly one argument.
