Something did indeed: numpy.ma.MaskedArray is now a subclass of ndarray, and 
inheriting from MaskedArray should follow the rules of ndarray subclassing. 
You'll find a brief overview of subclassing at this link:
http://www.scipy.org/Subclasses
In short,  you can't initialize it with a __init__, you need a combination of 
__new__ and __array_finalize__.

Don't hesitate to send me your class (at least the __init__ and a couple of 
specific methods) and I'll see how what I can do.
