Lazy.swift

class MyClass {
	lazy var property: String! = {
		println("Inside the initializer!")
		return "Fallback"
	}()
}


let obj = MyClass()

println("property: \(obj.property)")

obj.property = "Foo"

println("property: \(obj.property)")

obj.property = nil

println("property: \(obj.property)")


/**
Console output:

Inside the initializer!
property: Fallback
property: Foo
Inside the initializer!
property: Fallback

*/

y u use tab literals!? i thought you knew better!

Historical note: this is no longer the Swift Lazy behavior.

@a2: I reformatted it in GitHub.
