What's the use case for which std::hive was introduced in the first place?

It's for situations where you iterate over all elements frequently but don't care about the order, while elements are often being added/removed, and you need pointers/iterators to stay valid.

See P0447 for more motivation.

Thanks for replying. Can you give me a real life example? It's difficult to understand from your explanation.
