title: What does System.Double[*] mean
body: <p>This gem was created in some interop code which we decompiled. We can't figure out how to create an instance of this array, nor what type of array it is.</p>
  
  <p>Looking at <code>Type.GetElementType</code> gives me that it is an array of type <code>Double</code>, but we can't figure out how it is different from <code>System.Double[]</code>.</p>
