Yes, you're right, I was able to write *immutable* sequence using only the 
documentation but I had to look at MPL code to see how extensible sequences 
are implemented. After all, I decided to specialize push_front, pop_front, 
push_back and pop_back for function_arguments. And I asked primarely about 
documenting it (or may be there is a better way?).

That would be great.
