Turns out that the final version of Boost.Coroutine that made it into the 1.53 release has out-of-the-box support for treating the values returned by a coroutine as a range, which makes writing such an outputs_of() function trivial:

using boost::coroutines::coroutine; ... template coroutine outputs_of(F f) { return coroutine{[f](typename coroutine::caller_type& caller) { f(boost::make_function_output_iterator([&caller](const T& t){ caller(t); })); }}; }

A complete example using the two functions in your original post is attached.

The code uses some C++11 features like lambdas, but these can easily be translated to their C++03 equivalents if necessary. I'll leave it to you as an exercise to do that if you need to.

Hope that helps!

Regards, Nate

boost.coroutine required some fixes releated C++11 and iterators (thank you nate) - the fixes are applied to trunk and should be available in boost-1.54. Oliver
