Variadic @autoclosure's in Swift 1.2?

Question

Now that @autoclosure is part of the parameter declaration as opposed to type, how does one declare that a function takes a variadic amount of autoclosures?

Before:

public func coalesce<T>(all : @autoclosure () -> T? ...) -> T? {
    for f : () -> T? in all {
        if let x = f() { return x }
    }
    return nil
}

After: ???

I opened rdar://19782845, "Swift 1.2: Variadic auto-closures no longer supported," and was given the following response from Apple Developer Relations:

This issue behaves as intended based on the following:

@autoclosure is only allowed on parameters of function type, and varargs is an array. This is not expected to work.
