Containers library

One question for you /prog/!

Suppose you have a brand new language, which doesn't have any library yet. Which kind of basic containers / data structure would you expect?

There can be a big difference, overloading or not. Take clojure's hash maps. You don't have to do (make-hash (make-hash-pair "abc" 12) (make-hash-pair "dfg" 23)) etc.; since it's built-in you can use something like {"abc" 12, "dfg" 23}.
