// Iterate over its children MirrorItems
for item in mirror {
  println(item)
}
//name: Swift.String = Jon
//age: Swift.Int = 27

let children = mirror.children //Array of MirrorItem
let firstKid = children[0]
//{name: "name", type: Swift.String, value: "Jon" }

var mirP = mirror[1]
mirP.name   // "age"
mirP.value  // 27
mirP.type   // Swift.Int
