// The Swift Programming Language book from Apple states the following:
//
// Swift automatically provides shorthand argument names to inline closures, 
// which can be used to refer to the values of the closure’s arguments by the
// names $0, $1, $2, and so on.


// In Xcode 6.1 and 6.2b1, it appears that this is only true IF the last argument
// is referenced using shorthand syntax somewhere in the closure body. See below
// for details.
