--- Comment #2 from FranÃois Dumont <fdumont at gcc dot gnu.org> ---
Sure I can take care of it.

The Standard is saying that for any sequence type this insert operation shall
not take a range pointing back to the sequence. I plan to rather check the
libstdc++ limits as most of its containers allow this kind of insertion. For
the moment I think that only std::vector and std::deque are in this situation,
maybe std::string, I will double check.

The proposed use case is indeed a bit more complicated, I will see if I can
cover it too.
