Mmh, .reorder is not a regular ndarray method, so that won't work. What is it 
supposed to do ? And regrid ?

For set_fill_value, just use
m.fill_value = your_fill_value

For identity, just use the regular numpy version, and view it as a 
MaskedArray:
numpy.identity(...).view(MaskedArray)

For common_fill_value: ah, tricky one, I'll have to check.

If needed, I'll bring identity into numpy.ma. Please don't hesitate to send 
more feedback, it's always needed.
Sincerely,
P.
