   Hi, can mx.nd.where(condition, x, y) supports if both x and y are None, like [tf.where](https://www.tensorflow.org/api_docs/python/tf/where) and [np.where](https://docs.scipy.org/doc/numpy-1.13.0/reference/generated/numpy.where.html)?
   If both x and y are None, then this operation returns the coordinates of true elements of condition.

   Thanks!
