Re: [boost] auto_vector - vector with auto_ptr semantics

I'd like to see this.

I'd like even better to see it done as an adaptor that can wrap any
container of pointers/smart pointers. That could be used as the substrate
for the indirect linear associative container implementation we've discussed
here not long ago.
