It looks like blaze will have bit pattern missing values ala R. I don't know if there is going to be a masked array implementation. The NA code was taken out of Numpy because it was not possible to reach agreement that it did the right thing. Numpy.ma remains the only solution for bad data at this time. The code could probably use more love than it has gotten ;) Chuck
