thanks, news://news.gmane.org/gmane.comp.lib.boost.user helped, but
still have a  problem:

boost::function<void(const boost::shared_ptr<A>&)> deref =
boost::bind(&boost::shared_ptr<A>::operator*, _1);

Functor ftor;
std::vector<boost::shared_ptr<A> > vec = ...;
for_each(
        vec.begin(),
        vec.end(),
        boost::bind(
                boost::ref(ftor),
                boost::bind(&boost::shared_ptr<A>::operator*, _1)
        )
);//fine

for_each(
        vec.begin(),
        vec.end(),
        boost::bind(
                boost::ref(ftor),
                deref
        )
);//not fine. see error below
//no match for call to '(Functor) (boost::function<void ()(const
//boost::shared_ptr<A>&), std::allocator<void> >&)
