无法弄清楚是否可以使用Scalaz 7编写类似的内容.我试图用代码块中的注释表达自己.

def validate1(p: String) = ValidationNel[String, Value] = ...
def validate2(p: String) = ValidationNel[String, Value] = ...

validateCombination(p1: String, p2: String) = {
  // I would like to write something like
  (validate1(p1) |@| validate2(p2)) { (v1, v1) =>
    // And validate the combinations here and return successNel of failNel
  }
}

def validate(p1: String, p2: String, p3: String) = {
  (validateCombination(p1, p2) |@| validate1(p3)) { (v1, v2, v3) =>
    // Notice the three parameters I want to have here …
