Agreed, I’d also really like to see this some day. It seems like a natural outgrowth of the concurrency model, if it goes the direction of actors. If you’re interested, I speculated on this direction in this talk:

My interpretation is that he was advocating a future where a precondition’s failure killed less than the entire process. Instead, shut down some smaller portion like a thread, actor, or container like .Net's app domains (which for those more familiar with Javascript could be loosely compared with Web Workers).
Today - if you wanted a Swift server where overflowing addition didn’t interrupt your service for multiple users, you would need to use something like a pre-fork model (with each request handled by a separate swift process)
That's the difference between CLI and desktop apps where the process is providing services for a single user, and a server where it may be providing a service for thousands or millions of users.
