Comment (by marc.glisse@…):

 Ah, indeed you are right. In my case, I know the elements are unique. I
 guess it makes sense that I am responsible for using this extra
 information and I should write:
 {{{
 S s;
 s.reserve(v.size());
 s.insert(v.begin(),v.end());
 }}}
 Using a flat_multiset instead of a flat_set for speed reasons would be
 weird.
