Makes sense. And it works great when applied within one library, say 
Boost.Container. But then what about all the other container libraries 
in boost:

BiMap
CircularBuffer
Gil
MultiArray
MultiIndex
Unordered

etc.

We would have to have a Boost-wide trait for all interactions to be 
optimal. And then we can't do anything about interactions with the 
standard library.

Anyway, I don't feel strongly about it either way.

kind regards
