[Numpy-discussion] __eq__ with str and object

I don't understand this:

...

a1 = np.array(['a', 'b'], dtype=object) a2 = np.array(['a', 'b'])

a1 == a2

array([ True, True], dtype=bool) # Looks good

...

a2 == a1

False # Should I have expected this?

This works like I expected:

...

a1 = np.array([1, 2], dtype=object) a2 = np.array([1, 2])

a1 == a2

array([ True, True], dtype=bool)

...

a2 == a1

array([ True, True], dtype=bool)
