Write a proposal. It is trivial to add, clone(), checkpoint(), save(), restore() members to coroutine_handle<>. Coroutine handle is just a pointer to a blob of memory representing the current state of the coroutine. In fact, you can probably hack it up today using VS 2015 RTM, by providing your own allocator and learning the size and location of the memory block representing the coroutine state. Once you now it, you can pretty much do whatever you want with it. -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
