What is the current behavior?

When I try to export combineReducers, TypeScript throw the following error:

error TS4082: Default export of the module has or is using private name 'AnyAction'.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://jsfiddle.net or similar.

I simply export combineReducers

export default combineReducers({
  myReducerOne: oneReducer,
  myReducerTwo: twoReducer,
});

What is the expected behavior?

No error from typescript, we should be allowed to export combineReducers

Which versions of Redux, and which browser and OS are affected by this issue? Did this work in previous versions of Redux?

Typescript 2.4.1
Redux 3.7.2

I noticed the @private flag has been added yesterday as a comment in the definition code

/**
 * An Action type which accepts any other properties.
 * This is mainly for the use of the `Reducer` type.
 * This is not part of `Action` itself to prevent users who are extending `Action.
 * @private
 */
export interface AnyAction extends Action {
  // Allows any extra properties to be defined in an action.
  [extraProps: string]: any;
}

Typescript doesn't like this at all.
Any reason why this is flagged as private?

Regarding the all-too-common "has or is using private name" error, I've opened a request to fix issues like these in TypeScript by bringing declaration files to parity with language features. microsoft/TypeScript#35822
