title: Duplicate Identifier in duplicate module
body: <p>I have 2 files which contain the same module in my solution (different projects).
  </p>
  
  <pre><code>module myModule{
      export function doStuff(){} // in here "doStuff" is getting redlined
  }
  </code></pre>
  
  <p>This error is obviously because i have 2 files with the same piece of code in it. But seeing as they don't reference each other or anything for that matter, i don't see how they can conflict.</p>
