Can I make #selector refer to a closure in Swift?
<p>I want to make a <code>selector</code> argument of my method refer to a closure property, both of them exist in the same scope. For example,</p>

<pre><code>func backgroundChange() {
    self.view.backgroundColor = UIColor.blackColor()
    self.view.alpha = 0.55

    let backToOriginalBackground = {
        self.view.backgroundColor = UIColor.whiteColor()
        self.view.alpha = 1.0
    }

    NSTimer.scheduledTimerWithTimeInterval(0.5, target: self, selector: #selector(backToOriginalBackground), userInfo: nil, repeats: false)
}
</code></pre>

<p>However, this shows an error: <code>Argument of #selector cannot refer to a property</code>.</p>

<p>Of course I can define a new, separate method and move the implementation of the closure to it, but I want to keep it frugal for such a small implementation.</p>

<p>Is it possible to set a closure to <code>#selector</code> argument?</p>
