Well, it seems like a non-intrusive modification, but I like the scalars to remain un-indexable, mainly because it would be useful to raise an error when you are trying to index them. In fact, I thought that when you want a kind of scalar but indexable, you should use a 0-d array. So, my vote is -0. Cheers, -- >0,0< Francesc Altet http://www.carabos.com/ V V Cárabos Coop. V.
