module(examples.hello-world)
import(std.prelude)
import(posix.posix)

def(main, +World -- +World,
    "Hello, World!" put line)

Tak Benchmark Function

module(tak.main)
import(std.prelude)
import(std.str)
import(posix.posix)

def(tak, Int Int Int -- Int, 
  dup2 < if(
    dup3 1- tak 
    dip(dup3 rotr 1- tak)
    dip2(rotl 1- tak) 
    tak,
    drop2
  )
