Chaining actions and waiting for state updates?

What is the recommended way to chain actions where the second action is dependent on the first action to update the state?

For example. Selecting a country in a dropdown and then fetch a list of cities once one is selected.

This obviously doesn't work.

```js
selectCountry: (state, actions, country) => {
actions.readCities();
return { selectedCountry: country };
},
readCities: (state, actions) => {
state.selectedCountry; // etc...
}
```

The workaround I use now is to make country an optional argument of `readCities`, but I feel this is making the code needlessly complex. Especially with larger/complexer stores/actions.

```js
selectCountry: (state, actions, country) => {
actions.readCities(country);
return { selectedCountry: country };
},
readCities: (state, actions, country) => {
country = country || state.selectedCountry; // etc...
}
```
