Re: [boost] [iterators] Proof-of-concept for a sentinel iterator adapter

Attached is proof-of-concept code for a sentinel iterator adapter. It turns a pointer to sentinel terminated sequence, such as a C-style string, into a forward iterator with a conforming end iterator.

This is more efficient than doing a separate sequence traversal just to find the end.

I'm a little surprised that Boost doesn't already have such an iterator adapter. Or am I just missing it?

Would a production version of this iterator adapter be a worthwhile addition to Boost.Iterators?

Any other comments appreciated,

Yes !! Could be made even more generic as Joaquin noted, but other than that it would make a very useful addition. John.
