[Numpy-discussion] bug in numpy.apply_along_axis: numpy.__version__ '1.0.3.1'

My expectation was that array would iterate over a set. This is incorrect: array(set([1,2,3])) array(set([1, 2, 3]), dtype=object) Is this the intended behaviour? A trivial work-around that does what I need is array(list(set([1,2,3]))) array([1, 2, 3]) but I was wondering if this was
