Oh, yes, I read too fast and missed the part about random access, sorry.

I think the data structure presented here
http://www.eecs.usma.edu/webs/people/okasaki/pubs.html#fpca95 should
fulfill the requirements, but I don't know if it's been implemented in
Erlang.

The last element is queue:last(Q). ;-)
