XQuery reverse isn't implemented.  Instead, you're gettin the Scheme
version of reverse, which works on lists, rather than sequences.
Importing Scheme functions is/was a kludge that should get removed.
(My plan is that kawa/qexo-specific functions will have to use a
new kawa: or qexo: prefix, but I haven't implemented that yet.)

Implementing XQuery reverse is relatively hih priority, but I've been
concentrating on other things, including two workshop proposals.
Hopefully I'll get back to Qexo starting next week, while travelling
to/in Europe.
