I don't see any problem to provide it. I don't like much "base()" name, 
naybe I should rename the function to internal_container() or something 
similar.

Anyway, are not internal random-access iterators good enough?

flat_set_type::iterator itbeg = flat_set.begin();
const T& t1 = itbeg[0];
const T& t2 = itbeg[1];
