Hi all, in https://github.com/numpy/numpy/pull/3514 I proposed some changes to the comparison operators. This includes:
1. Comparison with None will broadcast in the future, so that `arr == None` will actually compare all elements to None. (A FutureWarning for now) 2. I added that == and != will give FutureWarning when an error was raised. In the future they should not silence these errors anymore. (For example shape mismatches) 3. We used to use PyObject_RichCompareBool for equality which includes an identity check. I propose to not do that identity check since we have elementwise equality (returning an object array for objects would be nice in some ways, but I think that is only an option for a dedicated function). The reason is that for example >>> a = np.array([np.array([1, 2, 3]), 1]) >>> b = np.array([np.array([1, 2, 3]), 1]) >>> a == b will happen to work if it happens to be that `a[0] is b[0]`. This currently has no deprecation, since the logic is in the inner loop and I am not sure if it is easy to add well there. Are there objections/comments to these changes?
