I've this in a dsource project:

http://svn.dsource.org/projects/dranges/trunk/docs/range2.html
(look for flatten or concat). 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!
