elpa-a binary package in Ubuntu Lunar amd64

 Library for dealing with associative data structures: alists,
 hash-maps, and vectors (for vectors, the indices are treated as
 keys).
 .
 This library is largely inspired by Clojure, it has many of the
 functions found in clojure.core, prefixed with `a-'. All functions
 treat their arguments as immutable, so e.g. `a-assoc' will clone the
 hash-table or alist it is given. Keep this in mind when writing
 performance sensitive code.
