I just realized today that this object has a bit of a problem. async::context isn't movable and if this inherits it, then its also not going to be movable. But having a version of a context that is movable seems very useful. We can consider this like a smart pointer where you need to use the
operator*()andoperator->()to access the context. That way, it just holds a pointer to the object and a pointer to the memory resource it used to allocate the memory.So this type will not inherit
async::contextbut instead will have an APIasync::context& operator*();.
