I found Stream.unfold to be quite useful for places where I don’t know how many iterations are needed to get to the end.

stream = Stream.unfold(10, fn x -> 
  if x != 0 do
    IO.puts "Hello"
    {:ok, x - 1}
  else
    nil
  end 
end)

Stream.run(stream)

There’s also Enum.reduce_while, but it needs an enumerable as input to start with.
