Yes if there's not one there for it already.

Yes, it is sponsored by https://github.com/kaleidicassociates it 
will be around for a long time.
It is developed separately because the dev/release cycles don't 
easily align with the core/ stdlib developers.

https://github.com/libmir/mir-algorithm/blob/master/source/mir/ndslice/slice.d#L594
is the de facto matrix structure for D.

Indeed, I'll see what I can do about it.
