[Boost-users] Facilities for view

Hi, I'm wondering if there is any facility to help define view in boost. There is view for static types http://www.boost.org/doc/libs/1_35_0/libs/fusion/doc/html/fusion/view.html. And there is a package to help define iterators http://www.boost.org/doc/libs/1_35_0/libs/iterator/doc/index.html. Due to the similarity between view and iterator, I'm wondering if there is a similar package for view? Thanks, Peng
