Beware: there are maps and then there are maps.
E.g. Javascript's objects are maps (typically thought of as being
implemented as some kind of hash-tables), yet Javascript also comes with
hash-tables.
More importantly, mathematical maps are persistent, whereas your
apparently favorite implementation (the hash-table) is not persistent,
contrary to (e.g.) alists.
