All container constructors should have a variant taking an allocator as a final parameter

Description
I am attempting to use the new allocator_traits functionality to facilitate a scoped_pointer work-alike. However, I am running into difficulties because there are a number of constructors that do not have a variant taking an allocator as a final parameter. For example, basic_string does not have a copy-constructor taking an allocator.
Thanks, Erik Jensen

Replying to igaztanaga:
Sorry, the scoped allocator model is not implemented yet, let's see if I can find time to bring it in Boost 1.50. Thanks for the ticket.
I know the model itself is not supported, but the new C++11 constructors are useful for more than just that, and it seems like implementation should be pretty simple. For example,
basic_string(const basic_string& s, const allocator_type& a) : base_t(a) { this->priv_range_initialize(s.begin(), s.end()); }
or
vector(const vector &x, const allocator_type &a) : base_t(a) { this->assign( container_detail::to_raw_pointer(x.members_.m_start) , container_detail::to_raw_pointer(x.members_.m_start + x.members_.m_size)); }
Of course, there are probably more complications that I am overlooking.
Thanks again for you consideration.
