Without making the assumption that my indices are zero based I think I can generally
write my loop as, (and please confirm this btw)

for (view_t::index i = * view.index_bases(); i != * view.shape(); ++i ) {.....}

but it seems a rather non-obvious and cumbersome expression. If view_t had
an indices() method that returned a list of index_range objects then I could
write

for(view_t::index i = view.indices()[0].start(); i != view.indices()[0].finish(); ++i ){.....}
