Hi Stephan,

Things would, I think, make much more sense if ndarray.__array_ufunc__ (or *_function__) actually were the implementation for array-only. But while that is something I'd like to eventually get to, it seems out of scope for the current discussion. But we should be sure that the ndarray versions return either NotImplemented or a result.

Given that, I think that perhaps it is also best not to do NotImplementedButCoercible - as I think the implementers of __array_function__ perhaps should just do that themselves. But I may well swing the other way again... Good examples of non-trivial benefits would help.

All the best,
