title: Is there any `itemgetter` equivalent for `numpy.ndarray`?
body: <p>When I call <code>itemgetter</code> with a <code>numpy.ndarray</code>, I get a <code>tuple</code>.</p>
  
  <pre><code>In [1]: import numpy as np                                                    
  In [2]: import operator as op                                                 
  In [3]: ar = np.array([1,2,3,4,5])                                            
  In [4]: op.itemgetter(1,3)(ar)                                                
  Out[4]: (2, 4) 
  </code></pre>
  
  <p>I wonder if there's any numpy function that's like <code>itemgetter</code> but returns an <code>ndarray</code> instead.</p>
