title: Typed Array as Function Parameter not possible - why?
body: <p>Why is this possible:</p>
  
  <pre><code>interface MyInterface{
  
      aggregate: (Array) =&gt; Array&lt;string&gt;;
  }
  </code></pre>
  
  <p>But not this:</p>
  
  <pre><code>interface MyInterface{
  
      aggregate: (Array&lt;string&gt;) =&gt; Array&lt;string&gt;;
  }
  </code></pre>
