// Swift in beta 4
if (optional?.methodReturningBool()) {
    println("awesome")
}

// Swift in beta 5
if (optional != nil && optional!.methodReturningBool()) {
    println("damnit...")

// Why not have our cake and eat it too?
// This would be great:

var optional: Bool = nil
println("optional?") // false
optional = false
println("optional?") // true
println("optional") // false
