I've tried to use this before, but an IndexError (0-d arrays can't be indexed) is raised. > * Ellipses x[...] and x[..., newaxis] This, especially, seems like it could be very useful. > This is an easy change to implement, and I don't think it would cause > any backward compatibility issues. > > Any opinions from the list? This is maybe a fairly esoteric use case, but one I can imagine coming across. I'm in favour of implementing the change. Could I ask that we also consider implementing len() for 0-d arrays? numpy.asarray returns those as-is, and I would like to be able to handle them just as I do any other 1-dimensional array. I don't know if a length of 1 would be valid, given a shape of (), but there must be some consistent way of handling them.
