Didn't think about that, but I'd say why not.

Likely not at all, i.e. you'd get an error either at runtime or at compile
time (if doable). It would also be possible to consider a
multi-dimensional view a view on a recursive sequence instead (like tuples
of tuples), so that it would concatenate the first dimension. I'm open to
both, depending on what use cases we come up with (meaning: if we don't
currently care, this would be an error until further consideration).
