It certainly makes sense that views would *usually* be read-only, but is
that really a *requirement*? attrview(), recently discussed in
Python-Dev, allowed changing the underlying object. See Martin v.
Lowis's implementation of attrview() here:
http://mail.python.org/pipermail/python-dev/2007-February/071044.html
It allowed setting attributes on the underlying object, like this:
attrview(self)[method_name] = attrview(self.metadata)[method_name]
