8101	coroutine's iterator doesn't have postfix ++ operator	Nathan Ridge	olli	"The following code fails to compile:

{{{
#include <iostream>
#include <iterator>
#include <boost/coroutine/coroutine.hpp>
#include <boost/range/algorithm/copy.hpp>

typedef boost::coroutines::coroutine<int()> coro_t;

void foo(coro_t::caller_type& caller)
{
    caller(0);
    caller(1);
    caller(2);
}

coro_t f()
{
    return coro_t(&foo);
}

int main()
{
    boost::copy(f(), std::ostream_iterator<int>(std::cout, ""\n""));
}
}}}

The reason is that std::copy (which is called by boost::copy) uses the postfix version of the iterator's increment operator, but the coroutine's iterator only provides the prefix version.

One way to write an iterator class that satisfies all the iterator interface requirements with minimal work is to use iterator_facade (http://www.boost.org/doc/libs/1_53_0/libs/iterator/doc/iterator_facade.html)."	Bugs	closed	To Be Determined	coroutine	Boost Development Trunk	Problem	fixed
