I am shocked to discover that boost::begin() etc, does not seem to work for boost::scoped_array.

Is there a reason for this?

How would boost::end be implemented? boost::scoped_array doesn't know the size of the array.

Quite. So there would seem to be quite a bit of benefit to having scoped_array hold its own size. I guess the objection might be that it makes scoped_array bigger than a c-array, but the difference is pretty small.

But if you don't care about small differences, why use scoped_array instead of std::vector?

Good point - and a killer argument, which I should have thought of, but didn't because I didn't write the code from scratch. Thanks muchly! - Rob.
