Concurrent main.swift?

Using Swift
1

After a half-hour of googling, I haven't been able to find a good answer. Is there any way to make an SPM project with a main.swift file entry point execute in a concurrent/async context? I can do it with something like this:

AppMain.swift:

@main
struct
AppMain
{
	static
	func
	main()
		 async
		 throws
	{
		try await someTask()
	}
}

But I'd like to do it like this:

main.swift:

try await someTask()

(Swift doesn't allow the presence of @main and a main.swift in the target.)

Right now this isn't possible but the proposal to enable this is under active review: SE-0343: Concurrency in Top-level Code

Thanks. Looking at that again, I remember reading it before. I love the desired implementation ("just works"). Looking forward to it.
