It will certainly help. In the meantime however... > I have experimented (actual working code) with what you're > looking for.

Check out the DynObj class in the NoPtr library at noptrlib.sourceforge.net (which provides smart ref rather than smart pointer, but that`s irrelevant to the issue). > NTL ( http://www.ntllib.org/ ) claims to have this today (I think).

Interesting ideas but a number of things would be a problem for many, at least at first glance (only random access, move semantics for container copy, etc).
