This have advantage when the container is not available, only iterators
void one_two_three(Iter begin, Iter end)
assert(distance(begin, end) >= 3);
copy(on_fly % 1 % 2 % 3, on_fly_end<int>(), begin);
It has some serious problem, though. For example, in
find(on_fly % 1 % 2 % 3, on_fly_end<int>(), 2);
return value points to temporary.
