title: Assigning a Iron Python list to .NET array
body: <p>I have a list comprehension operating on elements of an .NET array like</p>
  
  <pre><code>obj.arr = [f(x) for x in obj.arr]
  </code></pre>
  
  <p>However the assignment back to obj.arr fails.</p>
  
  <p>Is it possible to convert a list to a .NET array in IronPython?</p>
