Philippe Sigaud: Hello, it seems you have re-done with ranges for D2 a good amount of things I did for D1: http://www.fantascienza.net/leonardo/so/libs_d.zip
- bimap/nmap/map: having a single map able to do all that is better. The same for filters. - setComprehension: better to have a set(range). - comprehension: see select() in my dlibs. Bye, bearophile
