8024	Unable to create const_iterator for coroutine	Nathan Ridge	olli	"It seems to be impossible to create a const_iterator for a coroutine. For example, the following fails to compile:

{{{
#include <boost/coroutine/coroutine.hpp>

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

void f(coroutine_type::caller_type& c) {}

int main()
{
    coroutine_type c(f);
    coroutine_type::const_iterator it = boost::begin(c);
}
}}}

with the error:


{{{
test.cpp: In function 'int main()':
test.cpp:10:55: error: conversion from 'boost::range_iterator<boost::coroutines::coroutine<int()> >::type {aka boost::coroutines::detail::coroutine_op<int(), boost::coroutines::coroutine<int()>, int, 0>::iterator}' to non-scalar type 'boost::coroutines::detail::coroutine_op<int(), boost::coroutines::coroutine<int()>, int, 0>::const_iterator' requested
}}}
