Want even more confusion ?
>>> x = ma.array([1,2,3],mask=[0,1,0], dtype=int)
>>> x[0].dtype
dtype('int64')
>>> x[1].dtype
dtype('float64')
>>> x[2].dtype
dtype('int64')
Yet another illustration of the masked constant... The more I think
about it, the more I think we should have a specific object
("MaskedConstant") that would do nothing but tell us that it is masked.

No idea, as I still haven't figured why you were having the problem in
the first place

assert(np.arccos(ma.masked), ma.masked) would be the simplest.
