The Y combinator:
var y = ->(f) {->(g) {g(g)}(->(g) { f(->(*args) {g(g)(args...)})})}
var fac = ->(f) { ->(n) { n < 2 ? 1 : (n * f(n-1)) } }
say 10.of { |i| y(fac)(i) } #=> [1, 1, 2, 6, 24, 120, 720, 5040, 40320, 362880]
var fib = ->(f) { ->(n) { n < 2 ? n : (f(n-2) + f(n-1)) } }
say 10.of { |i| y(fib)(i) } #=> [0, 1, 1, 2, 3, 5, 8, 13, 21, 34]ASCII generation of the Sierpinski triangle:
func sierpinski_triangle(n) {
var triangle = ['*']
{ |i|
var sp = (' ' * 2**i)
triangle = (triangle.map {|x| sp + x + sp} +
triangle.map {|x| x + ' ' + x})
} * n
triangle.join("\n")
}
say sierpinski_triangle(4)Output:

ASCII generation of the Mandelbrot set:
func mandelbrot(z, r=20) {
var c = z
r.times {
z = (z*z + c)
return true if (z.abs > 2)
}
return false
}
for y in (1 `downto` -1 `by` 0.05) {
for x in (-2 `upto` 0.5 `by` 0.0315) {
print(mandelbrot(Complex(x, y)) ? ' ' : '#')
}
print "\n"
}Output:
