ah ok, so does that mean that if the user specified a std::vector to be
used for flat_set via the Container template param then it would not work
because std::vector is missing these methods or are they used behind the
standard vector interface?

if so i don't think the new Container param would be the best idea, maybe
just have that as unconfigurable (as now), but accessible via a
storage_type typedef.

right, gotcha
