[swift-corelibs-dev] Better integration with UNIX tools

[Tony Parker]

Of course, Foundation API has no way of distinguishing if the caller is considered a script or not.

If the API is a bad idea for other kinds of apps then we simply wouldn’t add it. So, I think this proposed convenience API needs to consider all of the varied clients of Foundation.

Swift scripts don't typically invoke `RunLoop.run()` or `dispatch_main()`, and without changing the way they generate main() functions to intrinsically do so (and then schedule main.swift's body on the main runloop/queue), I don't see a good way for it to do so. So an async API would be inconvenient to use from a Swift script.
