Infinite, yes, but I would say it's not quite as core to the language as it is in Haskell where everything's lazy. Infinite streams are quite simple though:

  Stream.iterate(1, fn(x) -> x end) 
  |> Enum.take(5)
  [1, 1, 1, 1, 1]

How do you use that for lists that do not simply iterate, like

    ghci> fibs = 0 : 1 : zipWith (+) fibs (drop 1 fibs)
    ghci> take 10 fibs
    [0,1,1,2,3,5,8,13,21,34]
?

You can use Stream.unfold/2:

  Stream.unfold({0,1}, fn {a,b} -> {a,{b,a+b}} end)
  |> Enum.take(10)
  [0, 1, 1, 2, 3, 5, 8, 13, 21, 34]
