Operator ||| like as ||

gistfile1.scala

class CondOp(val a: Boolean) {
  def |||(b: => Boolean) = if (a) a else b
}

object Main {
  def main(args: Array[String]) {
    implicit def boolWrapper(cond: Boolean) = new CondOp(cond)
        
    true  ||| { println("hoge"); false }
    false ||| { println("foo"); true}
  }
}

lean to scala in "by-name-parameters".
