For that, we need a proper RFC that lays out the plan. This RFC can be informed by the experience and working implementation, so we should have a lot of data to use. It's being merged into nightly (behind a flag) to gain understanding of how the feature would work. This isn't the day to celebrate Rust having fully-fledged co-routines coming soon to stable because there is no such guarantee yet. Edit: removed extra word
