What is the state of container libraries? I am looking for a library which provides:
* unordered containers (for "operational" type safety, I don't want to impose orders on things that don't have them -- unordered containers does this)
You are imposing an order.
* can handled nested containers (containers does that) * can be serialized easily, or better yet, has Generic instances
Does such a library exist? What are you using for Set and Map needs?
What's wrong with 'containers' itself? I prefer Map/Set over HashMap/HashSet, because the speed difference is small and only noticable for large maps/sets. If you need multiple indices, there is IxSet. The advantage of those is that their speed and memory behavior is more predictable, and they're not subject to hash collision attacks. Serializing them is done by importing your favorite serialization package, be it binary, cereal or safecopy/acid-state. They all have the necessary instances. For all these reasons I'm not a big fan of hash-based data structures, particularly hash tables. Greets, Ertugrul -- Not to be or to be and (not to be or to be and (not to be or to be and (not to be or to be and ... that is the list monad.
