此代码不匹配.它是否正确？
List(1, List(2, 3, List(4)), 5) must containTheSameElementsAs(List(5, List(List(4), 2, 3), 1))
错误消息如下:
[error] x be available for elements in a sequence
[error] List(1, List(2, 3, List(4)), 5)
[error] is missing: List(List(4), 2, 3)
[error] must not contain: List(2, 3, List(4)) (specs2test.scala:98)
