It should be possible to create zero-width Arrays.

buy why?

I also ran into this when updating the reshape implementation. NumPy allows Arrays with zero dimensions. When I asked Ritchie, he said to keep this constraint of size > 0 for now. But I guess ideally we would support this. Not really a bug though.

Just to note: if we do support this, the reshape implementation can be updated to allow zero dimensions.

If we were to fully support the array counterpart of .list.concat, I guess the length 0 array (acting as the identity) makes sense and will have its virtue for many application. We can do no-op for list counterpart with length 0 lists.
