From there, the only quesion is when an operation on a bytes or str object should return such a view, and the answer would be never. Return views from view objects, the non-views from non-view objects. If you want views, wrap your original object with a view, and call its methods. If you need a non-view, call the standard bytes/str constructor.

I do like the idea of permitting multiple string implementations, some of which might store their characters elsewhere, as lists and large tables do.

But this needs to be an automatic implementation detail, like the distiction between int and long. If the choice must be explicit, then people who worry too much about speed will start wrapping all string references in view(). This is worse (and more tempting) then the default-argument len=len hack.
