Me too. It solves some nice problems.

Thanks! (It's a layered container solution.)

But sometimes that's exactly what you want, a data collection to appear as
some other group. Also it fits well with the STL algorithms which want a
c.begin(), c.end() range.

Makes a great "smart" iterator, and a poor container, IMO not a good
candidate for a VTL type because it manipulates a stream not a container.

Screws and nails, smart iterators and views, the right tool for the job.
