раз пошла такая пьянка...

(10x centralasian)

не то чтобы я слишком понимаю смысл происходящего на этом свете...

(at last some good news from my pathetic coding experiments)

  val appender = (s1: String) => (s2: String) => s1 + " " + s2

  "ApplicativeSet" should {
    "combine Johns and Pauls" in {
      import All.AppSet._
      val combinations = pure(appender) <*> Set("John", "Paul") <*> Set("the 1st", "the 2nd")
      combinations equals Set("John the 1st", "John the 2nd", "Paul the 1st", "Paul the 2nd") mustBe true
    }
  }

from a log
