for print in exampleany {

switch print {

case let someInt as Int:

println("Integer value is \(someInt)")

case let someDouble as Double where someDouble > 0:

println("Pi value is \(someDouble)")

case let someString as String:

println("\(someString)")

case let phy as Chemistry:

println("Topics '\(phy.physics)', \(phy.equations)")

default:

println("None")

}

}
