Yeah: cache a value in the iterator with boost::optional<value_type>. Put a new value in the cache when the iterator is incremented.
Good suggestion! I'll post the modified code if anyone is interested. Actually, though, I was wondering if anyone had a more elegant approach in a more general sense, to the problem of transforming some kind of source into a sequence. Possibly "range" could be useful, but I don't know.
