Blocking concern: this function should not be stabilized before the working group has been able to complete a feasibility study of async overloading, as that may mean that we may no longer have an std::stream submodule. Instead we'd likely fold the functionality of std::stream into std::iter, exposing this as std::iter::pending instead.
