Incorrect Span behaviour

[yeyan]

java> List.of(1,1,2,2,1,1).span(x -> x == 1)
(List(1, 1), List(2, 2))
// It should (List(1, 1), List(2, 2, 1, 1)) The list is simply truncated here
java> List.of(1,1,2,2,4,4).span(x -> x == 1)
(List(1, 1), List(2, 2, 4, 4))

It seems it is using map behind the scene.
I am using version 2.0.2

Thanks for reporting! I will investigate and fix it.

Iterator#takeWhile and Iterator#dropWhile are broken:

1. They continue to apply the given Predicate, even if the test returned false
2. null is used to indicate 'no more elements' but null is a valid element
