// We want the root state to be an ImmutableRecord, which is an object with a defined list of keys,
// so it is properly typed and keys can be accessed using `state.<key>` syntax.
// This will allow an easy conversion to a plain object once we no longer call `get` or `getIn` on the root state

// By default with `combineReducers` it is a Collection, so we provide our own implementation to get a Record
