Subject: [boost] Offering sorted_vector for Boost, any interest?

I've come across lots of code that uses std::set where I think a
sorted vector would perform better. Those places a characterized by:
1. fills the set only once,
2. just wants to drop duplicates or
3. calls set::find very often.
Facing such code I often wished there was a ready to use sorted_vector
I think a new container that stores elements in a vector instead of a
tree offers strong advantages:
a. one call to std::sort instead of managing a red-black-tree
b. less memory overhead
c. better data locality for lookup
Possible things that I currently consider:
- - offer one-time initialization read-only sorted container?
- - offer mutable container with std::set-like interface (complexity
- - offer taking contents from std::vector for init without copying
- - offer equivalent to std::map also?
- - provide a pointer container, too?
Is there general interest in such a container? I'd like to develop an
implementation and offer it to Boost.
