title: redux-observable epic with multiple filters
body: <p>I am writing an epic using redux-observable and am trying to write an epic using multiple filters (oftype).  Given below is my sample code</p>
  
  <pre><code>export const landingEpic = action$ =&gt; {
      console.log('inside landing epic');
      return action$.ofType('APPLY_SHOPPING_LISTS').map(() =&gt; (
          {
              type: 'APPLYING_SHOPPING_LISTS',
          })
      );
  
      return action$.ofType('APPLIED_SHOPPING_LIST'){
        //here I want to return something else
      }
  }
  </code></pre>
  
  <p>However I cannot have two return methods in one epic?</p>
