Weakable

//Given a class
class TestClass {}
//and an instance of that class
var aTestObject = TestClass()

//You can create a Weak like this:
var weakTestObject = Weak(aTestObject)

//Or using the shorthand operator ≈
var anotherWeakTestObject = ≈test

weakTestObject.object //returns your value as an optional, since it may or may not have been released

//Given an object
let object = AwesomeClass()

//you can create a Weak by either
var weakObject = Weak(object)

//or
var weakObject = ≈object

//Given a Weak
var weakObject = ≈object

//you can access the underlying object by
weakObject.object

//or
weakObject≈

//Given a Weak
var weakObject = ≈object

//you can change the underlying object by
weakObject.object = anotherObject

//or
weakObject ≈ anotherObject

var tests = (1...10).map { TestClass() } // 10 elements
var weakTests = tests.map { ≈$0 } // 10 elements

tests.removeLast() // `tests` now have 9 elements, but `weakTests` have 10

weakTests = weakTests.filterWeaks() // `weakTests` now have 9 elements too, since we dropped the released objects from it

let tests = weakTests.compactWeaks()
