Nobody has suggested inventing or implementing yet another anything.     All I want to do is separate out the ndmasked array as a separate object and leave the ndarray object alone.

I think points 2 and 3 are fine as long as the 1.7 release does not have masked array notions attached to all ndarray objects.
