MiddlewareArray.prepend/concat methods don't handle array arguments correctly

[markerikson]

Per example at reduxjs/redux-thunk#333 (comment) and https://codesandbox.io/s/react-redux-toolkit-wbzkgc?file=/src/store/index.ts , it looks like gDM().prepend([someMiddleware]) doesn't handle type extraction right and the store falls back to Dispatch<AnyAction>:

const store = configureStore({
  reducer: {
    UserReducer: UserReducer,
    // // Uncomment me and get type error in file "./src/hooks/index.tsx"
    [APISlice.reducerPath]: APISlice.reducer
  },
  middleware: (getDefaultMiddleware) =>
    getDefaultMiddleware()
      .prepend([UserAPIListenerMiddleware.middleware])
      .concat([APISlice.middleware])
});

I suppose we either ought to reject arrays entirely at runtime, or modify the types to deal with that.

I take it back. We do have typetests for this, but you do need to mark the array as const, and I can see that the resulting dispatch type is right (and that if I remove as const it fails).

Gonna close this.
