Lambda Spiral

The (archimedean) spiral is formed by a lambda expression shown below. It performs computation similar to `[1, 2, 3].map(elem => elem - 1)` (JavaScript).

`(f => (x => f(n => x(x)(n)))(x => f(n => x(x)(n))))(m => l => f => (_ => _)((l => l(_ => _ => (_ => f => f(_ => _))))(l))(_ => (_ => (f => _ => f(_ => _))))(_ => (h => t => (l => r => f => f(l)(r))(h)(t))(f((p => p(l => _ => l))(l)))(m((p => p(_ => r => r))(l))(f))))((e => (l => (f => (x => f(n => x(x)(n)))(x => f(n => x(x)(n))))(v => r =>
