Yes, lambda functions are Turing-complete. You can get anonymous recursion by defining the function to take a recursive function argument and then passing it to itself. For example, this will (inefficiently) give you the 13th Fibonacci number: (lambda f, n: f(f, n))(lambda f, n: n if n < 2 else f(f, n-2) + f(f, n-1), 13)
