Wanna bet they don't?  ```python  In [2]: test = np.ma.MaskedArray([True, True], mask=[False, True])  In [3]: assert_equal(test, [True, True])  # correct, as before  In [4]: assert_equal(test, [True, False])  # uh oh...  In [5]: assert_equal(test, [True, np.array("oh dear", dtype=object)])  # oh geez  ```
