Clojure is a language that really puts the "high" in high level. It is quite difficult to trace a Clojure expression back to what will happen on the CPU - and the innovations on things like vector storage are part of that.

It was a bold decision with the potential to cause pain, but Clojure's vectors are great fun to work with. The "novel" basic data structures get out of the way and generally cause more joy than pain. It is part of a fundamental strategy enabling a strongly immutable style which really pays off when it works in concert with the rest of the language.
