title: Numba - TypeError: 'type' object has no attribute '__getitem__
body: <p>I am using Numba with Anaconda and wondering why</p>
  
  <pre><code>@jit(argtypes=[int16[:], int16[:]])
  def index(ic, nc):
      return ic[0] + nc[0] * (ic[1] + nc[1] * ic[2])
  </code></pre>
  
  <p>does not work:</p>
  
  <pre><code>TypeError: 'type' object has no attribute '__getitem__'
  </code></pre>
  
  <p>But if I use <code>@autojit</code> instead of <code>@jit(..)</code> everything is fine.</p>
