Yes, when is the way to do loops in this language. From the hidden examples page

  functi fibonacci (n) => {
     const var sum = 1!
     const var i = 0!
     when (i < n) {
        sum += sum + previous sum!
        i++!
     }
  }

  when (i < 10) {
     fibonacci(i)?
     i++!
  }

And if you don't want your code to loop back by accident you can just use lifetimes! Truly an elegant language

Oh please tell me you can specify the length of your loops in lines of code executed.

[ravi-delia]

  var var i<10> = 0!!
  var var i = false!
  when (i) {
    print(i)!
    i++!
  }

I think this should print 0,1,2 and then stop, assuming checking the condition is a line of code, and that lifetimes are for lines executed and not just the syntax.
