Hi Eric.

I've downloaded the SEGMENTED_FUSION_V2 and searched for anything with
"segement" in the filename, but found nothing.  I also tried:

cd ~/boost-cvs/ro/boost/sandbox/fusion/cvs/FUSION_V2/spirit/boost/
find . -name \*.hpp -exec grep segment {} \; -ls

with no results.  I'm thinking of using these segmented iterators
instead of what I'm currently using in http://tinyurl.com/pgoh4.
The iterators corresponding to segmented iterators there are
the ones with member functions first_non_empty and next_non_empty.
I think my current implementation may be close to what Austern
described as the inefficient seg_array_iter on p. 6 of the
paper you cited earlier:

  http://lafstern.org/matt/segmented.pdf

in the boost-devel list.  Obvously I would like to use the
more efficent one that you're developing.  Is there any
chance you could upload the code so I could have a look
and see if I could adapt it for my use.

TIA.

-regards,
Larry
