[Numpy-discussion] Expected behavior of np.array(..., copy=True)

Can anyone shed some light on the expected behavior of code using array(..., copy=True) with pandas objects? We ran into this in statsmodels and I think there are probably plenty of places where we explicitly call array(..., copy=True) and think we should have a totally independent copy of the data

I think one aspect that would be hard to think about is how the tiling would happen when broadcasting from K -> N where N/K is an integer. There are at least 2 different ways to tile that would produce different results. Suppose you have the array [[1, 2, 3]] which is (1,3). If you wanted to bro
