Hi Roland,

[I'm sending this message both to the list and to you personally in case you 
don't read the list regularly].

I'm wondering what's the status of your "views" library, which is now in Boost 
sandbox?

I'm rather interested to use it and see in in Boost, and I have some 
questions:

1. Do you plan to work on it anytime soon and push it to review?
2. It (specifically filter_iterator) does not work for me (see the attached 
compile log). Is there any change you'll fix the problems? Will it be OK if I 
fix the problems?
3. I would have expected that there is some common 'view' class which provides 
definitions for typedefs and functions like 'empty' and that individual views 
only define methods which really differ, like begin/end. Was this design ever 
considered.
4. Together with filter_view, I'd like to have 'filter' function, so that I 
can do something like:

    for_each(
          filter(vertices(g), boost::lambda::bind(out_degree_f, _1, g) == 0),
          .....);

Is it possible add such functions?
