Hi,
In the end some further API additions turn out to appear needed:
* NPY_ITER_COPY_IF_OVERLAP, NPY_ITER_OVERLAP_NOT_SAME
flags for NpyIter_New.
* New API function PyArray_MapIterArrayCopyIfOverlap,
as ufunc.at needs to check overlaps for index arrays
before constructing iterators, and

There remains the option to just let subclasses deal with new ndarray
features... Certainly, for `Quantity`, I'll quite happily do that.
And if it alllows the ndarray code to remain simple and efficient, it
is probably the best solution. -- Marten
