Thanks for pointing me about that. I am well aware about the fact, and 
had a long discussion in cpp news group, and finally thought to have a 
private inheritance rather than composition :)
Here is the link.

Just for information , in this thread someone asked about the status of 
the boost circular_buffer library. It also has a container called 
circular_buffer_space_optimized which privately inherit from 
circular_buffer (a decorator class ) .
  I really stl container to be final, AND really dislike stl container 
to be polymorphic (I am not sure anyone uses it in that way, if they do, 
they are BAD persons ! ). Thus it SAFE to have a non-polymorphic 
derivation of stl container.

and thanks again
