[boost] Re: Interest: Pointer Container Library

Not sure if this might be a good idea, but here it goes:

Would it make sense to have pointer container specializations for 
auto_ptr<>, shared_ptr<> and weak_ptr<>, simply as a way of specifying the 
desired semantics?

I'm thinking, for instance,

ptr_vector< auto_ptr<X> > would compile to same code, basically, as 
ptr_vector<X>, except: it would take auto_ptr<> as input, and return 
auto_ptr<> through functions that would otherwise return a pointer.

ptr_vector< shared_ptr<X> > would allow pointer containers to share 
ownership, and would interface via shared_ptr<>'s;  and...

ptr_vector< weak_ptr<X> > might give us the advantage of simplified 
algorithmic syntax, etceteras, but not take ownership.

Just a thought.
Cheers!
