Dan told me that he actually fixed this f*tag already sometime ago.
It was, in fact, already touched in the review. However, the change 
happened at a time when sourceforge had a failure (yeah I remember
that). There were some changes lost and he had to recreate some from
his local copy. Seems the f*tag issue was a victim of this outage.

Please hang on. Dan is in vacation now, but he'll fix it as soon as
he gets back. Anyway, I also have an iterator-adapter (iterator_facade),
sequence_facade and view_facade in the works. With it, it is easier
to write your own iterators, sequences and views. These will be
built on top of the tag dispatching scheme.

Keep rollin'..........
