I haven't heard it called "key-value" before, just referring to #Clojure maps, Python dictionaries, JS objects. Some of these old lisps are awkward at making these things, though.
@worldsendless Some people call this an association list. alist in Common Lisp doesn't look as concise as Clojure map. However, it has a few upsides too, for example, it keeps history of the same key in one list.
