Use default arguments naming

[kostiakoval]

When I call a NSTimer.after and pass a function, it doesn't have a argument name for second argument. This feels not natural for me regarding that all other functions usually used default or external names.

  NSTimer.after(1.second, close)

Using default names don't change the nice trailing closure syntax

public class func after(interval: NSTimeInterval, block: () -> Void) -> NSTimer 
...
NSTimer.after(1.second) {
  print("done")
}

If you agree I can make a PR :)

Thanks, but I think that's unnecessary. It reads quite naturally as the passed methods are going to be named with verbs generally. No need for verbosity.
