It's a lazy range. Flatten depends on a template for wrapping code, present in the traits2 module. http://www.dsource.org/projects/dranges/browser/trunk/range2.d http://www.dsource.org/projects/dranges/browser/trunk/traits2.d Hmm, this is waiting for quite an update. I've lots of thing for producing/mapping/filtering... ranges of ranges while conserving their topology/rank. If you find anything useful for you in this project, tell me! Philippe
