Because Or has two types, but the Bad factory method only takes a value of the “bad” type, the Scala compiler will
infer Nothing for the Good type:
scala> Bad("oops")
res1: org.scalactic.Bad[Nothing,String] = Bad(oops)
Often Nothing will work fine, as it will be widened as soon as the compiler encounters a more specific Good type.
Sometimes, however, you may need to specify it. In such situations you can use this factory method, like this:
scala> Good[Int].orBad("oops")
res3: org.scalactic.Bad[Int,String] = Bad(oops)
