#1025: Incorrect documentation for put function
------------------------+---------------------------------------------------
 Reporter:  afoglia     |       Owner:  somebody         
     Type:  defect      |      Status:  new              
 Priority:  normal      |   Milestone:  1.3.0            
Component:  numpy.core  |     Version:  none             
 Severity:  minor       |    Keywords:  put documentation
------------------------+---------------------------------------------------
 The documentation for the put method is incorrect.  In particular the
 psuedocode should read

 ind = array(indices, copy=False)
 vals = array(values, copy=False).astype(a.dtype)
 for i, v in zip(ind,vals): a.flat[i] = v

 In particular, it's the last line.  The i-th element of the array a is not
 filled with the i-th element of the values array, but the value that is
 next in the values array.

 If the documentation were correct as written, then a.put(indices,
 values)[indices] == values would not be guaranteed (up to nans).
