   Example:

   1. scala> import sclib.util.union._
      scala> def f[A: (Int Or String)#Check](a: A): Int = a match {
           |   case i: Int => i
           |   case s: String => s.length
           | }
      scala> f(5)
      res0: Int = 5
      scala> f("hey")
      res1: Int = 3
      // this throws a compiler error:
      scala> f(5L)
