If NEP 21 is accepted ( https://numpy.org/neps/nep-0021-advanced-indexing.html) this would be even simpler:
out.vindex[:, x] = 1
Was there ever a decision about that NEP? I didn't follow the discussion too closely at the time.
IIRC, I think there was broad agreement on the final plan as stated in the NEP. I suspect, though, that the general appetite for adding to the array API surface has declined even from its anemic starting point, now that deep learning frameworks with ndarray-mimicking APIs have taken off.
True, I am not sure on which side we would land now. Although, NumPy's advanced indexing is too odd to expect ndarray-mimicking APIs to copy it. At least with new attributes you have a chance to define clearly what should happen.
I personally still have appetite for it. But expect there will be enough "small" things to fix-up (improve the NEP, figure out how subclassing should be done, clean-up the old code) that this is still a decent sized project. The old 80-20 problem, I guess...
So, it just never quite reached the motivation/priority threshold for me since the original push.
