The result is some type that renders as a sequence of sequence using writeln but how to reduce it to a sequence? reduce isn't defined on MapResult and if I transform to an array reduce is not defined on SortedRange[]. Rust ownership problems seem to be a doddle compared to this problem. -- Russel. ============================================================================= Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Road m: +44 7770 465 077 xmpp: rus...@winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder
