Actually, the authors of Boost.Range got the idea from an earlier range library of mine, which is noted in the Acknowledgements section of the Boost.Range documentation [here](http://www.boost.org/libs/range/doc/html/range/history_ack.html http://www.boost.org/libs/range/doc/html/range/history_ack.h...): > Eric Niebler contributed the Range Adaptor idea which is arguably the single biggest innovation in this library.
