A mock replacing a PPField now behaves differently in the PPField.data call (in pp.py).
It used to have
isinstance(data, biggus.Array), to which Mock replies 'False'.Now has
is_lazy_data(data), which translates tohasattr(data, 'compute'), to which Mock replies True.It seems that np.array(mock) is ok, but
np.ma.masked_array(mock)does something nasty.
