It is also possible to come up with impossible states for most standard library objects (std::vector, std::list) if you know how they are stored internally. However I'm not sure such code could be submitted to boost.

This is the stuff I am expecting in the first place: A nice and clean 
interface, and implemented in an efficient way.
