Yes, I think swap is a fundamental operation that proxies should
support. I put swap in my write-up of the requirements for Proxy.

The down side of the current formulation is that it rules out proxied
container's with value types that have members (unlike vector<bool>).
The question is whether this down side is compensated by the reduced
confusion/error potential. Unless there are real examples of such
proxied containers that people find usefull I would suggest that we
stay with the more conservative formulation.
