[boost] Iterator Adaptor Poll

Hi Everyone,

Have you tried to use iterator adaptors and found the documentation
wanting? I have recently updated the documentation in the CVS:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/boost/boost/libs/
utility/iterator_adaptors.htm?rev=HEAD

However, enough people have had problems approaching this library that I
thought it would be useful to ask about what would make a gentle
introductory example. Beman recently sent me the enclosed, but it seems to
define such an oddball toy iterator that I'm not sure it would be a very
good motivating example. I'm asking for input, especially from anyone who
has "gotten over the hump" so to speak, with iterator adaptors.

TIA,
Dave
