So this needs to be fixed.

This looks like a straight-up bug in
54b4dc7, which introduced that error
message. A shape of () is totally valid.

@87, would you have time to fix that?

@certik Already committed? The removal of NpyIter_IsScalar is a done deal.

Ok, cool. I am closing this pull request.

My bad, first NpyIter_IsScalar was added, then it was removed again. So it is still gone ;)

@seberg Does your work cover this? If so, just comment and close.

Yes, this should be superceded by gh-3104, so closing.
