Iiuc, Boost.Container implements slist but not forward_list.  I'd like
to suggest tweaking the following sentence.

"Boost.Container updates the classic slist container with C++11 features
like move semantics and placement insertion and implements it a bit
differently for the standard C++11 forward_list."
               ^^

It might be better to say "and implements it a bit differently than the
standard C++ forward_list." ?
 
I wondered if you had both an slist and a forward_list
implementation for a while and did some other checking to
figure out what was in the library.
