kata solutions #2

I'd be also interesting to search for solutions without using any module.

defmodule Span do
def sort(list, whatever_function) do
whileright(list, whatever_function, [])
end

defp whileright([head | tail], whatever_function, good) do
case whatever_function.(head) do
true -> whileright(tail, whatever_function, good ++ [head])
false -> {good, [head] ++ tail}
end
end

defp whileright([], _, good) do
{good, []}
end

end
