There is something you are overlooking in the Boost.Range library itself :)

That's it, thanks.
Hmm, but why is it producing a Single Pass Range? I would think it should naturally match the characteristics of the underlying Range.
Hmm... You're right, I see no reason why it needs to be a single pass range, and a quick look at boost/iterator/transform_iterator.hpp shows that transform_iterator (the iterator type wrapped by the range) does indeed leave alone the underlying iterator's traversal category. Perhaps it's just a mistake in the documentation? Regards, Nate.
