My stance is that push_back, for instance, should throw if it goes beyond
capacity. This is primarily for consistency with other containers. I would
say, if it proves useful, to have a non-throwing version by a different name
in addition to push_back that has undefined behavior when going beyond the
capacity. This would be similar to how vectors have both the operator []
overload and the "at" member function.
