import ReactiveCocoa
let a: MutableProperty<[Int]> = MutableProperty([])
a.signal.observeNext { array in
print("Array did change: \(array)")
}
a.value.append(1)
a.value.append(2)
a.value.removeAtIndex(0)
a.value.append(3)
a.value[0] = 3
// Output:

// Array did change: [1]
// Array did change: [1, 2]
