I don't think it is necessary to create the other object _from_
the default one. You could have copy behavior be the default,
and if you want a view of some array you simply request one
explicitly with .view, .sub, or whatever.
Since creating a view is "cheap" compared to creating a copy,
there is nothing sacrificed doing things in this manner.
