9760	coroutine's iterators don't have == operator with const qualifier	Masahiro Nawata <kamo.tanabota@…>	olli	"coroutine's iterators don't have operator== with const qualifier.
Therefore, the following code fails to compile:
{{{
#include <boost/coroutine/v2/coroutine.hpp>
#include <boost/range/adaptor/filtered.hpp>
#include <boost/range/iterator_range.hpp>
#include <iostream>

int main()
{
	using namespace boost;
	coroutines::coroutine<int>::pull_type c([](coroutines::coroutine<int>::push_type& yield) {
		for (int i = 0; i < 5; ++i) {
			yield(i);
		}
	});
	auto crange = make_iterator_range(begin(c), end(c));
	for (auto n : crange
            | adaptors::filtered([](int n){return n % 2 == 0;})) // the filtered adaptor needs const operator==.
        {
		std::cout << n << std::endl;
	}
}
}}}
In addition, the iterators don't also have const operator!=.
