Sorry, you had me terrified I had broken unordered_Xxx in the shipping product for a moment. There was a period where I broke the heck out of them after I implemented LWG 2156 because we didn’t do as good a job internally documenting the container’s invariants as we should have. Load...
We never use hash_set and unordered_set because they are generally very expensive (each insertion requires a malloc) and very non-portable.std::multiset is useful if you're not interested in elimination of duplicates, but has all the drawbacks of :ref:`std::set <dss_set...
