title: Typescript assign null to interface
body: <p>This might be a silly question, but I can't figure out how to set a value of <code>null</code> to variable declared to be of an interface type.</p>
  <p>Below is an example of what I mean:</p>
  <pre><code>interface IMyInterface {
      field: any;
  }
  
  let test:IMyInterface = null; // &lt;-- Compiler error: Type 'null' is not assignable to type 'IMyInterface'
  </code></pre>
