title: How to solve "destructuring. Missing annotation" in FlowType?
body: <p>The following code:</p>
  
  <pre><code>export const myFunction = ({ option1, option2 }) =&gt; {};
  </code></pre>
  
  <p>...gives:</p>
  
  <pre><code>destructuring. Missing annotation
  </code></pre>
  
  <p>I do not want to have to create a <code>Type</code> specifically for the options object supplied to <code>myFunction</code> - this seems unnecessary, adds noise to the code and and will be a maintenance headache - can I achieve this and eliminate this FlowType error, or is this "how FlowType works"?</p>
