I use <https://github.com/ijp/pfds/>.  It has queues, hash maps and tree 
maps (as in, sorted by key), heaps, deques and some list data type. 
More precisely, I have used (pfds bbtrees), (pfds queues) and (pfds hamts).

Guile also has (ice-9 vlist), which has a functional interface, but its 
implementation isn't purely functional and as a consequence isn't 
thread-safe.

greetings,
Maxime.
