Using the println statement, print out the value of the language element from the result tuple.

What is wrong with printIn statement?

tuples.swift 
func greeting(#person: String) -> (greeting: String, language: String) {
    let language = "English"
    let greeting = "Hello \(person)"

    return (greeting, language)
}

var result = greeting(person: "Tom")
var result = printIn(result.language)
