+1. I believe the proposal should be accepted.

However, cross-platform libraries would still need to write:

#if os(OSX) || os(iOS) || os(tvOS) || os(watchOS)
    import func ObjectiveC.autoreleasepool
#else
    func autoreleasepool<Result>(
        @noescape body: () throws -> Result
    ) rethrows -> Result {
        return try body()
    }
#endif

Charles Srstka suggested an @autoreleasepool attribute:
