Having views in a library module alleviates many of my objections. While I still worry that it will be overused, deque doesn't seem to be overused, so perhaps I should relax.

Another thought is that there will already be ways in which Py3k views could lead to inefficiencies if they're not used carefully. A keys() view of a dict, for example, will keep the values of the dict alive as well as the keys, unlike the existing keys() method.
