I'm trying to define any_pointer using dynamic_any library. Everything is
fine except lambda support. I can't compile this:
any_int_pointer begin, end; // see example below for details
std::for_each(begin, end, std::cout << x);
Lambda cannot deduce return type of *begin. What should I do? May be some
kind of traits or nested template should be defined for any?

// any_pointer.cpp
typedef boost::dynamic_any::any<
boost::mpl::list<
boost::dynamic_any::dereference_to<int>,
boost::dynamic_any::increment,
boost::dynamic_any::not_equal_to
>
> any_int_pointer;
int main()
{
any_int_pointer begin, end;
boost::lambda::placeholder1_type x;
std::set<int> s;
s.insert(2);
s.insert(1);
s.insert(0);
begin = s.begin();
end = s.end();
std::for_each(begin, end, std::cout << x);
std::cout << "Enter integers and then EOF\n";
begin = std::istream_iterator<int>(std::cin);
end = std::istream_iterator<int>();
std::for_each(begin, end, std::cout << x);
}
