There is a Boost.Range extension library called P-stade Oven which
provides this adaptor under the name "taken", and many other adaptors:
http://p-stade.sourceforge.net/oven/doc/html/index.html
There exists an effort to port the P-stade Oven library to Boost, called
OvenToBoost: https://github.com/faithandbrave/OvenToBoost.
If you are interested in seeing functionality like this in Boost, perhaps
you can consider contributing to this effort.
