It sounds like you're referring to my old range_ex library in the
Algorithms directory in the Boost File Vault, is that right?
Somewhat confusingly, there is a *different* range_ex.zip in the Boost
File Vault, but at the top-level, here:
That one appears to be an extension of my earlier work (which itself was
an extension of the work of several others ... range algorithms and
adaptors have been a long time in coming).
The good news is that this new range_ex library is currently in the
review queue. From the review schedule
(http://www.boost.org/community/review_schedule.html), it looks like
we're still looking for a review manager. Care to volunteer? At the very
least, you should have a look at this new version and let us know if it
meets your needs.
