It mostly has to do

1. with the design of range algorithms and their return value

2. with how the range adapters are implemented, for example, I was 
wrting my own filter_range class instead of using two filter_iterators 
to save space.
(The range adapters add super-slick syntax like

BOOST_FOREACH( int i, container | boost::reversed | boost::filtered( 
a_pred ) )
foo( i );
)

3. I wanted to have some neat syntax for zip_ranges

That said, the task is not tremendously hard :-) I will rate it 
easy-to-medium. If you have some time to through at it, it could be
a good way to get your first boost submission.

So let me know if you're up for the task, and then we can further 
discuss what needs to be done.

cheers
