Dispatch returns undefined in certain cases.

[tappleby]

I brought up this issue in rackt/redux#481.

Im not sure if this can be solved from a code point of view but it might be worth documenting the issue with dispatch result being undefined in certain cases.

• middleware needs to come after thunk, promise or any middleware where you expect a value to be returned.
• with non-thunk actions you will not be able to access the return value.

Perhaps worth listing redux-batched-subscribe as an alternative.

I agree. Especially since @tappleby removed redux-batched-updates from the Redux ecosystem docs: https://github.com/rackt/redux/commit/dee3f07f1e81ed2a49dc8a599f1ed8952c9dc8c2 Which is confusing because most of the issues and talk mentions redux-batched-updates.
