Thanks, as always, Steven.

While clever, Boost.Lamba seems like overkill for this extremely
simple task.  Is it your experience that it would generate code as
efficient as what I originally posted?

Do you feel that such functionality doesn't belong in Boost.Iterator?
I think it nicely complements function_output_iterator.
